Internet of Things Talking Devices Ram n Sangwan What is IoT? • The Internet of Things is the network of physical objects—devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity—that enables these objects to collect and exchange data. • Internet of Things can also be defined as 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. • In the IoT, ‘things’ are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information ‘sensed’ about the environment, while reacting autonomously to the ‘real/physical world’ events and influencing it by running processes that trigger actions and create services with or without direct human intervention. Many Names, One Concept • M2M-Machine to Machine • “Internet of Everything” -Cisco Systems • “World Size Web”-Bruce Schneier • “Skynet”-Terminator movie Tecnologies • RFID • WiFi IEEE 802.11 • Barcode e QR Code • ZigBee IEEE 802.15.4 • Sensors and smartphones RFID • Widely used in Transport and Logistics • Easy to deploy: RFID tags and RFID readers • The communication range and the frequency depends on the type of technology WiFi • Very common • Widely used both in indoor and outdoor environments • General purpose • Low cost • Highly interoperable • Maybe not a good solution in some special conditions Barcode e QR Code • Low cost • No technological difficulties • Several devices can read a barcode • Starting point for more complex systems • Example: price comparison ZigBee • Low cost • Very long battery life • Easy to deploy • Large number of nodes -up to 64770 • Can be used globally • Secure • Ideal for WPAN and mesh networks • Support for multiple network topologies Sensors and smartphones  In the near future almost everybody will probably have a smartphone  A smartphone isn't just a mobile phone that has access to the Internet  The iPhone has a lot of different types of sensors Top Applications • Traffic monitoring • Health • Security • Transport and Logistics • Daily life and domotics The IoT Market • As of 2016, 16.1 billion IoT units • Expected to grow to 28.1 billion IoT devices by 2020 • Revenue growth from $1.9 trillion in 2013 to $7.1 trillion in 2020 Why be concerned about IoT? • It’s just another computer, right? ◦ All of the same issues we have with access control, vulnerability management, patching, monitoring, etc. ◦ Imagine your network with 1,000,000 more devices ◦ Any compromised device is a foothold on the network Does IoT add additional risk? • Are highly portable devices captured during vulnerability scans? • Where is your network perimeter? • Are consumer devices being used in areas – like health care – where reliability is critical? • Do users install device management software on other computers? Is that another attack vector? People Connecting to Things Things Connecting to Things Wireless Sensor Networks How are the networks changing? • Extensions ◦ More nodes, more connections, IPv6, 6LowPan,... ◦ Any TIME, Any PLACE + Any THING ◦ M2M, IoT ◦ Billions of interconnected devices, ◦ Everybody connected. • Expansions ◦ Broadband • Enhancements ◦ Smart networks ◦ Data-centric and content-oriented networking ◦ Context-aware systems Future Networks “Thing” connected to the internet Why should I learn about IoT? • Business trend • Emerging technologies • Growing IoT Services and Application Opportunities Smart product sales Internet Connected devices Web of Things To achieve IoT we need a universal protocol to combine several heterogeneous devices. This protocol should be: simple, lightweight, loosely-coupled, scalable, flexible and standard. Sounds like the WEB Web of Things • Several technologies and protocols already available and widely accepted by the community: – HTTP, TCP, IPV6, XML, JSON, RSS, ATOM, REST, WS-*, URI, etc. • URI to make the objects easily identifiable and addressable • XML, WS-* and REST to allow the objects to expose their features and to communicate with external or centralized services • Simpler mashup Semantic Web  Objects are the resources  Ontologies for knowledge representation Issues • Privacy • Security The future of IoT • World sensor networks • Home automation and domotics • Daily life (traffic monitoring, shopping, etc.) • Tracking and shipping of goods • Health • Unpredictable developments...
