Evolución hacia IoT
• Desde la Web a la Web Social hacia IoT

12
Historia IoT
• El concepto de dispositivo
inteligente conectado fue
acuñado en 1982 con máquina
expendedora conectada en
CMU
• El artículo de Mark Weiser en
1991 "The Computer of the
21st Century", y los conceptos
académicos de UbiComp y
PerCom fueron el germen de
IoT
• El término IoT fue acuñado
por Kevin Aston del MIT en
1999

13
Internet of Things: Definition (I)
• Internet of Things (IoT) is a dynamic global network
infrastructure with self-configuring capabilities based on
standard and interoperable communication protocols where
physical and virtual “things” have identities, physical
attributes and virtual personalities and use intelligent
interfaces and are seamlessly integrated into the information
network.
from the IERC (the European Research Cluster on Internet of Things
http://www.internet-of-things-research.eu/)
– Things can range from tagged objects (RFID, NFC, QR codes, Barcodes,
Image Recognition) to Wireless Sensor Networks (WSN), machines,
vehicles and consumer electronics

14
Internet of Things: Definition (II)
• The internet of things (IoT) is the network of physical
devices, vehicles, buildings and other items—
embedded with electronics, software, sensors, and
network connectivity that enables these objects to
collect and exchange data
– Opportunity for more direct integration of the physical
world into computer-based systems, and resulting in
improved efficiency, accuracy and economic benefit
– Encompasses technologies such as Smart Grids, Smart
Homes, Intelligent Transportation and Smart Cities

15
6 facts about IoT
1. IoT is the term used to describe any kind of application that
connected and made “things” interact through the Internet
2. IoT is a communication network connecting things which
have naming, sensing and processing abilities
3. IoT is the next stage of the information revolution, i.e. the
inter-connectivity of everything from urban transport to
medical devices to household appliances
4. Intelligent interactivity between human and things to
exchange information & knowledge for new value creation
5. IoT is not just about gathering of data but also about the
analysis and use of data
6. IoT is not just about “smart devices”; it is also about devices
and services that help people become smarter

19
IoT = Sensors + Connectivity +
Processing for People

20
Internet de las Cosas
• Red universal de objetos interconectados
y direccionables basada en protocolos de
comunicación estándar
– IoT exhibirá un alto nivel de heterogeneidad,
combinando objetos de distinta funcionalidad,
tecnología o campos de aplicación
– Protocolos semánticos noveles serán
desarrollados para permitir a IoT escalar y
coordinar a los millones de objetos que nos
rodean
– RFID y redes de sensores proporcionan un
mecanismo de bajo coste y robusto de
identificación y sensibilidad al contexto
• El uso de Internet pasará de modelo
request/reply a push-and-process

21
Internet de las Cosas: mucho más
que cosas inteligentes

22
IoT: 3rd wave of Internet
• Key attributes that distinguish IoT from “regular” Internet, as
captured by Goldman Sachs’s S-E-N-S-E framework: Sensing,
Efficient, Networked, Specialized, Everywhere

23
Internet of Things (IoT) Promise
• There will be around 25 billion devices connected to the
Internet by 2015, 50 billion by 2020
– A dynamic and universal network where billions of identifiable
“things” (e.g. devices, people, applications, etc.) communicate
with one another anytime anywhere; things become context-
aware, are able to configure themselves and exchange
information, and show “intelligence/cognitive” behaviour

24
Internet of Everything (I)
• CISCO view: “From the Internet of Things (IoT), where we are today, we
are just beginning to enter a new realm: the Internet of Everything (IoE),
where things will gain context awareness, increased processing power,
and greater sensing abilities”
– IoE brings together people, process, data, and things to make networked
connections more relevant and valuable than ever before-turning information
into actions that create new capabilities, richer experiences, and
unprecedented economic opportunity.

Tipos de Internet de las Cosas
• Al menos dos sabores:
– Consumer IoT (CIoT): orientada a consumidores
– Industrial IoT (IIoT)
• Industria 4.0

31
Consumer Internet of Things (CIoT)
• The Consumer Internet of Things (CIoT) represents
the class of consumer-oriented applications where:
– Devices are consumer devices, such as smart appliances,
e.g. refrigerator, washer, dryer, personal gadgets such as,
fitness sensors, Google Glasses, etc.
– Data volumes and rates are relatively low
– Applications are not mission or safety critical, e.g., the
failure of fitness gadget will make you, at worse, upset, but
won’t cause any harm
– CIoT applications tend to be “consumer-centric”

40
Industrial Internet of Things (IIoT)
• The Industrial Internet of Things (IIoT)
represents industry-oriented applications
where:
– Devices are machines operating in industrial,
transportation, energy or medical
environment
– Data volumes and rates tend to be from
sustained to relatively high
– Applications are mission and or safety
critical, e.g. the failure of a smart grid has
severe impact on our life and economy, the
misbehaving of a smart traffic system can
threaten drivers
– IIoT applications tend to be “system centric”

41
Differences among IoT, M2M & CPS
• Not clear cut distinction, these terms are often used
interchangeably;
– M2M– Machine-to-Machine
• TelCo world origins, tied to the network implications of connecting
machines rather than people, explosion of # of connections with limited
bit-rate, ETSI is the main standardisation body; think of telemetry
applications
– M2M is the glue of the IoT
– CPS – Cyber Physical Systems
• Merging real and virtual (cyber) worlds, focusing on systems that based
on duly sampled representation of the physical world can intervene
through digitized actuators to change behaviours in the physical world;
think of car ABS
– CPS is the science bricks behind IoT
– IoT hailed as a broader concept, where the focus is more on wide
applications

42
Smart Grid
• A Smart Grid is an
electrical grid which
includes a variety of
operational and
energy measures
including smart
meters, smart
appliances,
renewable energy
resources, and
energy efficiency
resources.

45
Industry 4.0
• Industry 4.0, Industrie 4.0 or the fourth industrial revolution,
is the current trend of automation and data exchange in
manufacturing technologies.
– It includes cyber-physical systems, the Internet of Things and Cloud
Computing.
– Industry 4.0 creates what has been called a "smart factory".

47
Industry 4.0: Features
• Ingredients for paradigm shift in manufacturing: autonomous robotics, additive
manufacturing (3D printing), cloud computing and sensor technology (IoT)
• Opportunities for innovation in terms of:
– Smarter industrial processes
– New business models and
– Customised products
• The new technological wave builds on the concept of cyber-physical systems:
profound interaction of the real and virtual worlds in the manufacturing process

48
Top 5 IoT Trends to Look Forward
to in 20181. Trend #1 Digital Twin
– Virtual clone of the real-world thing. It is a looking glass into what’s happening within physical assets.
Allows product developers to create, test, build, monitor, maintain and service products in a virtual
environment
2. Trend #2 Blockchain
– Blockchain for IoT can transform the way business transactions are conducted globally by providing a
trustworthy environment. Advantages: a) build trust; b) reduce costs; and c) accelerate transactions.
3. Trend #3 Security
– As we rely on connected devices to make our lives better and easier, security is a must. All participants
in the IoT ecosystem are responsible for the security of the devices, data and solutions.
4. Trend #4 SaaS
– Many IoT implementations still require on-prem implementations. There will be more (and very clear)
instances where Software as a Service (SaaS) is a viable option.
5. Trend #5 Cognitive Computing
– For over a decade we’ve connected things with unique IP addresses. But the commoditization of
sensors, processors and memory now make it possible to makes everyday things more than just
connected … they can be intelligent. It increases the possibilities of what can be done with edge
analytics – making sensors capable of diagnosing and adapting to their environment without the need
for human intervention.

49
Blockchain in a nutshell 101
• A blockchain is a decentralized, distributed and incorruptible digital ledger that is used to
record transactions across many computers.
– Distributed network of computers (nodes)
– where each node contains a chain-of-blocks
– where each block contains a ledger with a list of transactions
– where each transaction is incorruptible (i.e. cryptographically secure)
– & is linked to the previous transactions for the resource it is representing.
• Exemplary use cases:
– Record exchange of money;
– Document the way goods move through a supply chain;
– Create and store contractual agreements.
• Main features:
– Distributed – the record is shared, and cannot be controlled by any single person.
– Permissioned – each participant has secure access to the record
– Secure (incorruptible) – records are safe from manipulation; consensus is required. Everything
stored on the blockchain is encrypted.
• H(this-block) = H(H(previous-block) + data-in-this-block)

51
Blockchain, how does it work?

54
Blockchain: IoT example (I)
• Imagine the journey a perishable foodstuff (say milk) takes from farm to consumer
– The dairy farm: milking and initial storage;
– Processing: transportation to a dairy processor for testing, pasteurizing and packaging;
– Transportation: shipping in refrigerated trucks to retailers like supermarkets or convenience stores;
– Retail: storage in a refrigerated display unit;
– Consumption: customer purchase and consumption.
• The difficulty with a supply chain like this one is that there isn’t a single,
synchronized record of the transaction from beginning to end.
– Blockchain is a single, synchronized, immutable record of every transaction, visible to everyone in the
supply chain.
– The blockchain ledger records the sequence of transactions from the beginning to the end of the
supply chain.
• URL: very interesting infographics about IoT and Blockchain at:
http://www.sepaforcorporates.com/payments-news-2/what-is-blockchain-5-
awesome-infographics/

55
• Example: instrumenting the supply-chain
– “transport of perishable food stuffs (such as milk) is regulated by specific
conditions that ensure it arrives at the point of purchase safely”
• IoT & Blockchain solution: Connected sensors for data transmission
– Individual packages containing milk are instrumented with an IoT-enabled
temperature sensor
– The sensor stores temperature data locally and sends it via an IoT Platform
to the blockchain
– The blockchain stores the temperature data, where it can be viewed by each
party to the transaction
• IoT with blockchain can help businesses keep tabs on the health of their
products at every stage of their journey through Smart Contracts.
– Those contracts stored on the blockchain could specify certain conditions that must be
met. Controlled temperature might be one of these.

56
Internet of Things: Challenges
1. To process huge amounts of data supplied by “connected
things” and to offer services as response
2. To research in new methods and mechanisms to find,
retrieve, transmit and process data dynamically
– Discovery of sensor data — both in time and space
– Communication of sensor data: complex queries (synchronous),
publish/subscribe (asynchronous)
– Processing of great variety of sensor data time-series and streams:
correlation, aggregation and filtering
3. Ethical and social dimension: to keep the balance between
personalization, privacy and security

79
IPv6 a key IoT enabler (I)
• Latest revision of the Internet Protocol (IP), provides an identification
and location system for computers on networks and routes traffic across
the Internet.
– Developed by the Internet Engineering Task Force (IETF) to deal with the long-
anticipated problem of IPv4 address exhaustion
• IPv6 is intended to replace IPv4, which still carries the vast majority of Internet
traffic.
– As of May 2018, the percentage of users reaching Google over IPv6 surpassed 22%:
https://www.google.com/intl/en/ipv6/statistics.html#tab=ipv6-adoption&tab=ipv6-
adoption
• To make the switch, software and routers will have to be changed
• IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4×1038
addresses, or more than 7.9×1028 times as many as IPv4, which uses 32-bit
addresses.
• IPv6 addresses are represented as eight groups of four hexadecimal digits
separated by colons
– E.g. 2001:0db8:85a3:0042:1000:8a2e:0370:7334

80
IPv6 a key IoT enabler (II)
• The future of IoT will not be possible without the support of IPv6
– The global adoption of IPv6 in the coming years will be critical for the successful
development of the IoT in the future
• The ability to network embedded devices with limited CPU, memory and
power resources means that IoT finds applications in nearly every field
– IoT systems could also be responsible for performing actions, not just sensing
things
• 6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area
Networks
– The 6LoWPAN concept originated from the idea that "the Internet Protocol could and
should be applied even to the smallest devices“ and that low-power devices with
limited processing capabilities should be able to participate in the Internet of Things.
– The 6LoWPAN group has defined encapsulation and header compression mechanisms
that allow IPv6 packets to be sent and received over IEEE 802.15.4 (Zigbee) based
networks.

81
IPv6 vs. IPv4
• Other important changes:
• No more NAT (Network Address Translation), Auto-configuration, no
more private address collisions, better multicast routing, simpler header
format, simplified, more efficient routing, true quality of service (QoS), also
called "flow labeling“, built-in authentication and privacy support, flexible
options and extensions, easier administration (say good-bye to DHCP)

83
HTTP 2.0
• HTTP 2.0 is the next planned version of the HTTP network protocol used
by the World Wide Web.
– HTTP 2.0 is being developed by the Hypertext Transfer Protocol Bis (httpbis)
working group of the IETF.
– Based on Google's SPDY protocol, Microsoft's HTTP Speed+Mobility proposal
(SPDY based)
• HTTP 2.0 would be the first new version of the HTTP protocol since HTTP
1.1 was described by RFC 2616 in 1999.
– In May 2015 it was published as HTTP/2 as RFC 7540
• Goals:
– Include asynchronous connection multiplexing, header compression, and
request-response pipelining, while maintaining full backwards compatibility
with the transaction semantics of HTTP 1.1
– Enable Server-Push
• Documentation:
– http://chimera.labs.oreilly.com/books/1230000000545/ch12.html

84
HTTP 2.0 streams, messages and frames
Binary Framing Layer Stream, Messages & Frames
A connection carries any number of bidirectional
streams. In turn, each stream communicates in
messages, which consist of one or multiple frames,
each of which may be interleaved and then
reassembled via the embedded stream identifier in
the header of each individual frame
Request & Response Multiplexing

Radio Frequency Identification (RFID)

88
Near Field Communication (NFC)
• Near field communication (NFC) is a set of standards for smartphones and
similar devices to establish radio communication with each other by touching
them together or bringing them into close proximity, usually no more than a few
centimeters
– Operates at 13.56 MHz, has data transfer rate ranging from 106 kbit/s to 424 kbit/s
– NFC tags contain data and are typically read-only, but may be rewriteable
• Uses RFID (Radio Frequency Communication) chips that enable devices to
communicate between them, bi-directionally.
– Application examples:
• NFC headsets and electronic wallets, eliminates the need to pair devices in Bluetooth
or WiFi Direct (e.g. Android Beam / S-Beam), data exchange through NFC tags
• Wider availability of NFC-enabled SmartPhones is propelling its usage:
http://www.nfcworld.com/nfc-phones-list/
– Apple iPhone 6 to 8s supports NFC as part of Apple Pay

89
NFC in Use
• Get info from posters,
make payments,
exchange connections

90
Bluetooth Low Energy (BLE)
• Bluetooth low energy (BLE) is a wireless computer network technology which
is aimed at novel applications in the healthcare, fitness, security, and home
entertainment industries.
– Compared to "Classic" Bluetooth, it is intended to provide considerably reduced
power consumption and lower cost, while maintaining a similar communication
range
• Power consumption is drastically reduced via a low pulsing method that keeps devices
connected without the need of a continuous information stream
• Features:
– Operates in the same spectrum range (the 2.400 GHz-2.4835 GHz ISM band) as
Classic Bluetooth technology, but uses a different set of channels.
– Uses a star topology
– Nodes act as presence/state indicators
– Internet enabled devices as Gateways
• Available devices supporting BLE (most of the new SmartPhones feature it)

91
• In the market, we can encounter two types of BLE devices:
– Bluetooth Smart Ready refers to devices that use a dual-mode radios, which
can handle both the 4.0 technology, as well as classic Bluetooth abilities, such
as transferring files, or connecting to a hands-free device.
– Bluetooth Smart represents a new breed of Bluetooth 4.0 peripherals: sensor-
type devices like heart-rate monitors or pedometers that run on small
batteries and are designed to collect specific pieces of information.
• Only connect to BT Smart Ready devices

92
iBeacon – a class of BLE devices that broadcast their
identifier to nearby portable electronic devices (I)

Short range communication: NFC,
QR and iBeacons

96
• Sigfox, is a French company that builds wireless networks to connect low-energy objects such as electricity
meters, smartwatches, and washing machines, which need to be continuously on and emitting small
amounts of data
• Employs "a cellular style system that enables remote devices to connect using ultra-narrow band (UNB)
technology", the same used for submarine communications during World War I.
• The Sigfox network and technology is aimed at the low cost machine to machine application areas where
wide area coverage is required
• Its network costs are reduced and it requires little energy, being termed Low-power Wide-area network
(LPWAN)
– Sigfox uses long waves transmitting small amounts of data very far being able to handle approximately 12 bytes per
message, and at the same time no more than 140 messages per device per day
• With 12 bytes one can represent any number between 1 and 79 octillion, which translates as a myriad control codes
• According to Machina Research, in 2024 there were a total of 27 billion M2M connections or 80 billion
connected objects, 14% of which will represent LPWA connections like those offered by Sigfox and its
competitors (LoRa and Neul (Huawei))

• The Web of Things (WoT) is a computing concept that
describes a future where everyday objects are fully
integrated with the Web.
– The prerequisite for WoT is for the "things" to have embedded
computer systems that enable communication with the Web, i.e. HTTP
microserver
– Such smart devices would then be able to communicate with each
other using existing Web standards: HTTP & REST
– http://www.webofthings.org/

99
Web of Things (II)
• Term used to describe approaches, software architectural
styles and programming patterns that allow real-world
objects to be part of the World Wide Web
– Similarly to what the Web (Application Layer) is to the Internet
(Network Layer) the Web of Things provides an Application Layer that
simplifies the creation of Internet of Things applications
– Rather than re-inventing completely new standards, the Web of Things
reuses existing and well-known Web standards used in the
programmable Web (e.g., REST, HTTP, JSON), semantic Web (e.g.,
JSON-LD, Microdata, etc.), the real-time Web (e.g., Websockets) and
the social Web (e.g., oauth or social networks).

100
Web of Things Architecture
• The following layers compose WoT:
– Layer 1 (ACCESS): ensures things
have a Web accessible API,
transforming them into
programmable things
– Layer 2 (FIND): reuses Web
semantic standards to describe
things and their services
– Layer 3 (SHARE): data generated by
things can be shared in an efficient
and secure manner
– Layer 4 (COMPOSE): integrates the
services and data offered by things
into higher level Web tools

101
The Programmable World
• Los siguientes pasos para alcanzar la quimera de
Programmable World:
1. Transformar los objetos cotidianos en inteligentes
2. Conectar estos objetos entre ellos y hacer que
“conversen”, algo de lo que productos como SmartThings
están tratando
3. Construir aplicaciones basadas en esta conectividad,
interconectándolas con datos externos para predecir, por
ejemplo, patrones de tiempo o consumo eléctrico
• Soluciones como IFTTT facilitan esa conectividad
entre diferentes canales de datos

102
IFTTT
• IFTTT is a service that lets you create powerful connections
with one simple statement:
– IFTTT is pronounced like “gift” without the “g”
• Channels are the basic building blocks of IFTTT: Facebook,
Evernote, Email, Weather, LinkedIn
• Each channel has its own Triggers and Actions:
– The this part of a Recipe is a Trigger, e.g. “I’m tagged in a photo on
Facebook”
– The that part of a Recipe is an Action, e.g. “send me a text message”
– Pieces of data from a Trigger are called Ingredients
• Demos: https://ifttt.com/myrecipes/personal

103
Atooma
• Es como un IFTTT pero para
SmartPhones
• Permite definir eventos
condicionales (IF) que lanzan
automáticamente tareas (DO)
asociadas actividades que pueden
ser detectadas por tu móvil (hora,
localización, estado de la batería,
etc.)

104
IoT & Cloud Computing
Interdependency
• Cloud computing and IoT are tightly coupled
– The growth of IoT and the rapid development of
associated technologies create a widespread connection of
“things.”
• Leads to production of large amounts of data, which needs
to be stored, processed and accessed
– Cloud computing as a paradigm for big data storage and
analytics
• The combination of cloud computing and IoT will
enable new monitoring services and powerful
processing of sensory data streams.

105
Infraestructura Virtualizada:
Cloud Computing
Un paradigma de computación emergente donde los datos y servicios
residen en centros de datos muy escalables que pueden ser accedidos
ubicuamente desde cualquier dispositivo conectado a Internet.

106
Cloud Computing es …
• … capacidad computacional y
almacenamiento virtualizada expuesta
mediante infraestructura agnóstica a la
plataforma y accedida por Internet
– Recursos IT compartidos en demanda, creados y
eliminados eficientemente y de modo escalable a
través de una variedad de interfaces programáticos
facturados en base a su uso

107
Arquitectura Cloud Computing

108
Ventajas y Retos de Cloud
Computing

109
Cloud Computing Limitations for IoT
• Connectivity to the Cloud is a MUST but …
– Some IoT systems need to be able to work even when connection is
temporarily unavailable or under degraded connection
• Cloud Computing assumes that there is enough bandwidth to
collect the data
– That can become an overly strong assumptions for Industrial Internet
of Things applications
• Cloud Computing centralises the analytics thus defining the
lower bound reaction time of the system
– Some IoT applications won’t be able to wait for the data to get to the
cloud, be analysed and for insights to get back

110
Edge Computing
• Pushing the frontier of computing applications,
data, and services away from centralized nodes to
the logical extremes of a network.
– It enables analytics and knowledge generation to occur at
the source of the data.

111
Edge Computing: Benefits
• Locally confines regional data processing of M2M/big data applications
that incur large data traffic to edge-servers, and reduces network
bandwidth.
– Executes real-time applications that require high-speed response at the
nearer edge-servers which will satisfy the severe real-time requirement.
• Offloads some of the computation intensive processing on the user’s
device to edge servers and makes application processing less dependent
on the device’s capability.

112
Fog Computing = IoT + Cloud Computing (I)
• The software industry’s three building blocks, subject to Moore’s law, are:
storage, computing and network
– The problem is, right now everything is sorted in the cloud, which means you
have to push all this data up, just to get the distilled big data feedback down.
• Fog computing is a decentralized computing infrastructure in which
computing resources and application services are distributed in the most
logical, efficient place at any point along the continuum from the data
source to the cloud
o improve efficiency and reduce the amount of data
that needs to be transported to the cloud for data
processing, analysis and storage.
o done for efficiency reasons, but it may also be
carried out for security and compliance reasons.

113
Fog Computing = IoT + Cloud
Computing (II)

114
Web Semántica
• Problema de la Web Actual:
– El significado de la web no es comprensible por máquinas
• Web Semántica  crea un medio universal de
intercambio de información, aportando semántica a
los documentos en la web
– Añade significado comprensible por ordenadores a la Web
– Usa técnicas inteligentes que explotan esa semántica
– Liderada por Tim Berners-Lee del W3C
• Misión  “turning existing web content into
machine-readable content“

115
Web of Data: Limitaciones de la Web
de Documentos
• Demasiada información con muy poca estructura y
hecha además para consumo humano
– Es una web sintáctica no semántica
– La búsqueda de contenidos es muy simplista
• Se requieren mejores métodos
• Los contenidos web son heterogéneos
– En términos de contenido
– En términos de estructura
– En términos de codificación de caracteres
• El futuro requiere integración de información inteligente

116
Linked Data
• “A term used to describe a recommended best practice for
exposing, sharing, and connecting pieces of data, information,
and knowledge on the Semantic Web using URIs and RDF.“
• Allows to discover, connect, describe and reuse all sorts of data
– Fosters passing from a Web of Documents to a Web of Data
• In September 2011, it had 31 billion RDF triples linked through 504 millions of
links
• Thought to open and connect diverse vocabularies and semantic
instances, to be used by the Semantic community
• URL: http://linkeddata.org/

117
Linked Data Principles
1. Uses URIs to identify things
2. Uses HTTP URIs to enable those
things to be dereferenced by both
people and user agents
3. Provides useful info (structured
description and metadata) about a
thing/concept referenced by an URI
4. Includes links to other URIs to
improve related information
discovery in the web

Linked Data Life Cycle
• Linked Data must go through several stages (several
iterations on Linkage) before are ready for exploitation:

120
Schema.org
• Initiative launched in 2011 by Bing, Google, Yahoo and then Yandex
• Objective: “create and support a common set of schemas for structured data
mark-up on web pages.”
– Propose to use their schemas to annotate contents in a web page with metadata
• Metadata are recognized by search engines and other parsers, thus accessing to the
“meaning” of portals
• Their vocabularies were inspired by earlier formats like Microformats, FOAF,
GoodRelations and OpenCyc
• Offer schemas in the following domains
(http://schema.org/docs/schemas.html):
– Events, health, organization, person, place, product, offer, revisión and so on.
• To map declarations in microdata to RDF the following tools can be used:
http://tools.seochat.com/category/schema-generators
• More info at: http://schema.org/
• Examples:

– http://paginaspersonales.deusto.es/dipina/ (microdata.reveal Chrome plugin)

121
Avoiding Data Silos through
Semantics in IoT
• Cut-down semantics is applied to enable machine-
interpretable and self-descriptive interlinked data
– Integration – heterogeneous data can be integrated or one
type of data combined with other
– Abstraction and access – semantic descriptions are
provided on well accepted ontologies such as SSN
– Search and discovery – resulting Linked Data facilitates
publishing and discovery of related data
– Reasoning and interpretation –new knowledge can be
inferred from existing assertions and rules

122
Actionable Knowledge from
Linked Data
• Don’t care about the data sources (sensors) care about
knowledge extracted from their data correlation &
interpretation!
– Data is captured, communicated, stored, accessed and shared
from the physical world to better understand the surroundings
– Sensory data related to different events can be analysed,
correlated and turned into actionable knowledge
– Application domains: e-health, retail, green energy,
manufacturing, smart cities/houses

123
Data Understanding through Linked
Statistics & Visualizations

124
Bringing together IoT and Linked Data:
Sustainable Linked Data Coffee Maker
• Hypothesis: “the active collaboration of people and
Eco-aware everyday objects will enable a more
sustainable/energy efficient use of the shared
appliances within public spaces”
• Contribution: An augmented capsule-based coffee
machine placed in a public spaces, e.g. research
laboratory
– Continuously collects usage patterns to offer
feedback to coffee consumers about the energy
wasting and also, to intelligently adapt its
operation to reduce wasted energy
• http://socialcoffee.morelab.deusto.es/

125
Social + Sustainable + Persuasive +
Cooperative + Linked Data Device
1. Social since it reports its energy consumptions via social
networks, i.e. Twitter
2. Sustainable since it intelligently foresees when it should be
switched on or off
3. Persuasive since it does not stay still, it reports misuse and
motivates seductively usage corrections
4. Cooperative since it cooperates with other devices in order
to accelerate the learning process
5. Linked Data Device, since it generates reusable energy
consumption-related linked data interlinked with data from
other domains that facilitates their exploitation

126
Persuasive Interfaces to Promote Positive
Behaviour Change
GreenSoul, H2020
project 2016-2018, EE11

127
Linked Data by IoT Devices
• Modelling not only the sensors but also their features of
interest: spatial and temporal attributes, resources that
provide their data, who operated on it, provenance and so on
– With SSN, SWEET, SWRC, GeoNames, PROV-O, … vocabularies

128
Knowledge graphs:
Encyclopaedias for machines
• It consists of a formal description of certain knowledge that can be accessed and reasoned
about by computers
– fundamental to empower intelligent systems
• Apple’s Siri, Microsoft’s Cortana, Amazon Echo, or Google Now, for example, heavily rely on knowledge graphs
to fulfill your requests.
– a representation based on entities, relations, and facts.
• For example, the IMDb knowledge graph, meant to be used by both people and computers.
– Actors, directors, writers or films, are the entities while <acted_in> or <writer_of> some of
the relations. You can see the facts in each entity page.
• https://www.imdb.com/name/nm0424060/
• The range of questions (usually referred as queries) that can be asked to a knowledge graph
is broad. It can involve any combination of relations, entities, classes or facts.
– If the knowledge graph is relatively complete, it is guaranteed to provide high-quality answers in a
minuscule amount of time.
• The three most prominent general knowledge graphs to date: YAGO, DBpedia, and WikiData.

IoT como habilitador de las
Ciudades Inteligentes
• IoT allows for the pervasive interaction
with/between the smart things leading to an
effective integration of information into the digital
world.
– Smart things - instrumented with sensing, actuation, and
interaction capabilities - have the means to exchange
information and influence the real world entities and
other actors of a smart city eco-system in real time,
forming a smart pervasive computing environment to
achieve a more livable city

135
The need for Smart Cities
• Challenges cities face today:
– Growing population
• Traffic congestion
• Space – homes and public space
– Resource management (water and energy use)
– Global warming (carbon emissions)
– Tighter city budgets
– Aging infrastructure and population

136
What is a Smart City?
• Smart Cities improve the efficiency and
quality of the services provided by governing
entities and business and (are supposed to)
increase citizens’ quality of life within a city
– This view can be achieved by leveraging:
• Available infrastructure such as Open Government
Data and deployed sensor networks (IoT) in cities
• Citizens’ participation through apps in their
smartphones
– Or go for big companies’ “smart city in a box”
solutions

137
What is a Smart Sustainable City?
A smart sustainable city is an innovative city that uses
information and communication technologies and
other means to improve quality of life, efficiency of
urban operation and services, and competitiveness,
while ensuring that it meets the needs of present and
future generations with respect to economic, social and
environmental aspects
https://itunews.itu.int/en/5215-What-is-a-smart-sustainable-city.note.aspx

138
Smart City Applications
• sadfafd

139
• Smart Cities seek the participation of citizens:
– To enrich the knowledge gathered about a city
not only with government-provided or networked
sensors' provided data, but also with highly
dynamic user-generated data
• BUT, how can we ensure that users and their
generated data can be trusted and has enough
quality?
– W3C has created the PROV Data Model, for provenance
interchange
Citizen Participation

140
User-generated Data: Google Maps vs.
Open Street Map
• OSM is an excellent cartographic product driven by user contributions
• Google Maps has progressed from mapping for the world to mapping from the world,
where cartography is not the end product, but rather the necessary means for:
– Google’s autonomous car initiative, combine sensors, GPS and 3D maps for self-driving cars.
– Google’s Project Wing: a drone-based delivery systems to make use of a detailed 3D model
of the world to quickly link supply to demand
• By connecting the geometrical content of its Google Maps databases to digital traces
that it collects, Google can assign meaning to space, transforming it into place.
– Mapping by machines if not about “you are here”, but to understand who you are, where
you should be heading, what you could be doing there!

141
CrowdSensing
• Individuals with sensing and computing devices collectively
share data and extract information to measure and map
phenomena of common interest

142
Personal Data
• Defined as "any information
relating to an identified or
identifiable natural person
("data subject")”

143
Urban Intelligence / Analytics
• Broad Data aggregates data from heterogeneous sources:
– Open Government Data repositories and IoT deployments
– User-supplied data through social networks or apps
– Public private sector data or
– End-user private data
• Humongous potential on correlating and analysing Broad
Data in the city context:
– Leverage digital traces left by citizens in their daily interactions
with the city to gain insights about why, how and when they do
things
– We can progress from Open City Data to Open Data Knowledge
• Energy saving, improve health monitoring, optimized transport
system, filtering and recommendation of contents and services

144
Smarter Cities
• Smarter Cities  cities that do not only manage their
resources more efficiently but also are aware of the
citizens’ needs.
– Human/city interactions leave digital traces that can be
compiled into comprehensive pictures of human daily facets
– Analysis and discovery of the information behind the big
amount of Broad Data captured on these smart cities
deployment
Smarter Cities= Internet of Things + Broad Data + Citizen
Participation through Smartphones + Urban Analytics

IoT & Big Data
• IoT is also expected to generate large
amounts of data from diverse locations, with
the consequent necessity for quick
aggregation of the data, and an increase in
the need to index, store, and process such
data more effectively

Data has changed
• 90% of the world’s data
was created in the last two
years
• 80% of enterprise data is
unstructured
• Unstructured data growing
2x faster than structured

152
Nature of Data in IoT
• Heterogeneity makes IoT devices hardly interoperable
• Data collected is multi-modal, diverse, voluminous
and often supplied at high speed
• IoT data management imposes heavy challenges on
information systems

153
¿Qué es Big Data?
• "Big Data are high-volume, high-velocity, and/or high-variety
information assets that require new forms of processing to
enable enhanced decision making, insight discovery and
process optimization“ Gartner, 2012
– El término “Big Data” se originó dentro de la comunidad open source,
donde hubo un esfuerzo por desarrollar procesos de análisis que
fueran más rápidos y escalables que el data warehousing tradicional,
y pudieran extraer valor de los inmensos volúmenes de datos no
estructurados producidos a diario por usuarios web
• Es una oportunidad para encontrar percepciones en nuevos y
tipos emergentes de datos y contenidos, para hacer a tu
negocio más ágil, y para responder preguntas que fueron
consideradas con anterioridad fuera de tu alcance.

154
Big Data Evolution
• Data explosion!!
– 48 hours of data from stock market ~ 5 TB
– Semi and non-structured data provided in real-time through social networks
– Google processes PB/hour
• Bioinformatics – huge datasets about genetics and drugs
• Money whitening / terrorist funding, Spatial Data
• 85% of Fortune 500 organizations are not able to process Big Data to gain
competitive advantage – Gartner
• Currently more than 1.9 zettabytes of data are being produced

155
Necesidad de Big Data Analytics
• La percepción de los procesos de Data Warehousing es que
son lentos y limitados en escalabilidad
• La necesidad de converger datos de varias fuentes, tanto
estructuradas como no estructuradas
• Es crítico el acceso a la información para extraer valor de las
fuentes de datos incluyendo dispositivos móviles, RFID, la web
y otro largo listado de tecnologías sensoriales automatizadas.

IoT Data Processing
Architectures

165
Apache Hadoop
• Hadoop es una framework gratuita en Java para procesar grandes
volúmenes de datos en un entorno de computación distribuido
– Hace posible la ejecución de aplicaciones sobre sistemas con miles de nodos
que procesan miles de terabytes
– Su sistema de ficheros distribuido facilita la rápida transferencia de datos
entro nodos y permite al sistema seguir operando ininterrumpidamente en
caso de fallo de un nodo
– Inspirado por Google MapReduce, un modelo de computación donde una
aplicación se divide en varias partes
• Cada una de esas partes (fragmentos o bloques) puede ser ejecutada en cualquier
nodo de un clúster
– El ecositema actual de Apache Hadoop consiste de:
• Hadoop kernel, MapReduce, el sistema de ficheros distribuido de Hadoop (HDFS) y
otros proyectos relacionados como Apache Hive, HBase and Zookeeper.
– Usado por los grandes agentes de la industria Google, Yahoo and IBM

166
Apache Spark
• Apache Spark provides programmers with an application programming
interface centered on a data structure called the resilient distributed
dataset (RDD), a read-only multiset of data items distributed over a cluster
of machines, that is maintained in a fault-tolerant way.
– It was developed in response to limitations in the MapReduce cluster
computing paradigm, which forces a particular linear dataflow structure on
distributed programs
– Oriented to stream data processing allowing for CEP (Complex Event
Processing)

Summary: IoT Benefits (II)

170
IoT Market
• The global IoT market will grow from $157B in
2016 to $457B by 2020, attaining a Compound
Annual Growth Rate (CAGR) of 28.5%

171
Summary: Challenges of IoT (I)
• Platform : form and design of the products (UI and UX) , analytics tools
used to deal with the massive data streaming from all products in a secure
way , and scalability which means wide adoption of protocols like IPv6 in
all vertical and horizontal markets .
• Connectivity: Connectivity includes all parts of the consumer’s day and
night using wearables, smart cars, smart homes, and in the big scheme
smart cities.
• Business Model: The bottom line is a big motivation for starting, investing
in, and operating any business, without a sound and solid business models
for IoT we will have another bubble , this model must satisfied all the
requirements for all kinds of e-commerce; vertical markets, horizontal
markets and consumer markets.
• Killer Applications: Three functions needed in any killer applications,
control “things”, collect “data”, analyze “data”.
• Security: The IoT introduces unique physical security concerns implying
that IoT privacy concerns are complex and not always readily evident.

172
Summary: Challenges of IoT (II)
• Learn how to make money with it – make it
sustainable
– Finding meaningful use cases is key to success
– Visions are allowed, but first bills have to be paid
– New business models are key to making money with IoT
– Business models will have an impact on the architecture of
solutions!
• IoT can be complex!
– Keep it simple by structured data models and good scale
– Keep it understandable for customers and consumers

173
Summary: Challenges of IoT (III)
• Society: People, security, privacy
– A policy for people in the Internet of Things: Legislation (GDPR)
– Decisions – do not delegate too much of our decision making and
freedom of choice to things and machines
– Privacy and Security will distinguish between success and failure
– Managing one’s own privacy will become a complex task – and needs
to be kept simple
– Historical personal data availability – who will delete the data?
• Environmental aspects
– Resource efficiency
– Pollution and disaster avoidance
