3 Sensor devices are becoming widely available - Programmable devices - Off-the-shelf gadgets/tools 3

4 More Things are being connected Home/daily-life devices Business and Public infrastructure Health-care 4

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) 5

6 Change in Communication Technologies People Things 1G 2G 3G 4G 5G AMPS, NMT, TACS GSM. GPRS, TDMA IS-136, CDMA IS-95, PDC UMTS, CDMA2000, LTE, LTE-A 5G technologies and standards Voice Text Data Connection + Control M2M/IoT

7 The Internet of Things Applications Services/Interfaces Cloud Infrastructure Communication Devices Things

8 Some of the issues Applications Services/Interfaces Heterogeneity, domain knowledge, reusability, flexibility, maintainability, reliability, efficiency and scalability,. Interface definition, identification, pub/sub, semantics, query, composition, process management, command and control,. Heterogeneity Semantic Interoperability Cloud Infrastructure Back-end service, middleware/gateway solutions, discovery, access, directory services, security, access control, accounting,. Scalability Communication Heterogeneity of underlying devices, QoS, different data patterns and requirements (bandwidth and delay measure are not sufficient), Self-organisation Security/Privacy /Trust Devices Various hardware/software platforms, heterogeneity of communication technologies, energy/resource Energy-efficiency constraints, Things Describing the Things, Observation and Measurement and interaction attributes, Real-time processing Reliability
