Internet of Things: The story so far

  1. 1. Internet of Things: The story so far 1 Payam Barnaghi Centre for Communication Systems Research (CCSR) Faculty of Engineering and Physical Sciences University of Surrey Guildford, United Kingdom Conference on Rolling Plan on ICT Standardisation, March 2014, Bruxelles
  2. 2. 2 Network connected Things and Devices Image courtesy: CISCO
  3. 3. 3 Sensor devices are becoming widely available - Programmable devices - Off-the-shelf gadgets/tools
  4. 4. 4 More “Things” are being connected Home/daily-life devices Business and Public infrastructure Health-care …
  5. 5. 5 Internet of Things (IoT) − Extending the current Internet and providing connection, communication, and inter-networking between devices and physical objects, or "Things," is a growing trend that is often referred to as the Internet of Things. − “The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT)”
  6. 6. 1G AMPS, NMT, TACS 2G GSM. GPRS, TDMA IS-136, CDMA IS-95, PDC 3G UMTS, CDMA2000, 4G 5G LTE, LTE-A People Things Voice Text Data 5G technologies and standards Connection + Control M2M/IoT Change in Communication Technologies
  7. 7. The Internet of Things Things Devices Communication Cloud Infrastructure Services/Interfaces Applications
  8. 8. Some of the issues… Devices Communication Cloud Infrastructure Services/Interfaces Applications Things Describing the Things, Observation and Measurement and interaction attributes, … Various hardware/software platforms, heterogeneity of communication technologies, energy/resource constraints , … Heterogeneity of underlying devices, QoS, different data patterns and requirements (bandwidth and delay measure are not sufficient), … Back-end service, middleware/gateway solutions, discovery, access, directory services, security, access control, accounting, …. Interface definition, identification, pub/sub, semantics, query, composition, process management, command and control, …. Heterogeneity, domain knowledge, re- usability, flexibility, maintainability, reliability, efficiency and scalability , ….
