Internet of things& its need

• The transformation of Paradigm

• Extending network to “Things"

• Making network more Pervasive

• Application limited only by imagination

Page 4: Internet of Things for smart cities

Smart city Concept

• Efficient and effortless administration• Quality of service• Quality of living• Communication infrastructure

Page 5: Internet of Things for smart cities

Areas of exploiting IoT▸ Structural Health▸ Waste Management▸ Air quality▸ Noise Monitoring▸ Traffic Congestion▸ City Energy consumption▸ Smart lighting

Use of XML Parsing of messages Need for EXI Types of EXI

processors

Schema less encoding

Schema informed encoding

Data formats

Page 10: Internet of Things for smart cities

Application and Transport layers

▸ Problem with HTTP

▸ Need for CoAP

Page 11: Internet of Things for smart cities

Network layer▸ Present addressing scheme▸ IPV6 addressing scheme

Page 12: Internet of Things for smart cities

Wireless Connectivityo Frequency bands and

worldwide regulationso Communication Protocolso Network Rangeo Network Topologyo Standards and interoperability

Page 13: Internet of Things for smart cities

Frequency bands and worldwide regulations

▸ Can’t be limited to single frequency

▸ Common frequency 2.4 GHz

Page 14: Internet of Things for smart cities

Communication Protocols

Link

• Convert bits to radio signals

Network• Routes the data

Transport • Arranges the sessions

Application • End user controllability
