Introduction Different
architectures Web Service
Approach Wireless
Connectivity WSN requirements An experimental
Study
Internet of things& its need
• The transformation of Paradigm
• Extending network to “Things"
• Making network more Pervasive
• Application limited only by imagination
Smart city Concept
• Efficient and effortless administration• Quality of service• Quality of living• Communication infrastructure
Areas of exploiting IoT▸ Structural Health▸ Waste Management▸ Air quality▸ Noise Monitoring▸ Traffic Congestion▸ City Energy consumption▸ Smart lighting
“
Architecture
Sensing layer
Access layer
Middleware layer
Application layer
Architectural reference Model ITU proposed architecture
Web Service Approach ▸ Representational State Transfer
`
Protocol stack
Use of XML Parsing of messages Need for EXI Types of EXI
processors
Schema less encoding
Schema informed encoding
Data formats
Application and Transport layers
▸ Problem with HTTP
▸ Need for CoAP
Network layer▸ Present addressing scheme▸ IPV6 addressing scheme
Wireless Connectivityo Frequency bands and
worldwide regulationso Communication Protocolso Network Rangeo Network Topologyo Standards and interoperability
Frequency bands and worldwide regulations
▸ Can’t be limited to single frequency
▸ Common frequency 2.4 GHz
Communication Protocols
Link
• Convert bits to radio signals
Network• Routes the data
Transport • Arranges the sessions
Application • End user controllability
Network range & Topology
Standards & interoperability
Device framework
• Backend servers
• Gateways
• IoT peripheral Nodes
An Experimental Study
“▸ Collecting environmental data
▸ Monitoring Public street lighting
Places where IoT is incorporated
Smart Environment &Street lighting system▸ Geographical localization▸ Sensors used-Photometer
sensors▸ Form 6LoWPAN multihop cloud▸ IPV6 routing protocol provided▸ WSN gateway
A glance at temperature and humidity data
Data collected from Temperature and Humidity sensors
“Data collected from Photometer & quality check sensor
ConclusionTarget of different companies
Aims at shaping a better future
