7. Web Service Approach
▸Representational State Transfer
`

8. Protocol stack

9. Use of XML
Parsing of
messages
Need for EXI
Types of EXI
processors
Schema less
encoding
Schema
informed
encoding
Data formats

10. Application and Transport layers
▸Problem with HTTP
▸Need for CoAP

11. Network layer
▸Present addressing scheme
▸IPV6 addressing scheme

12. o Frequency bands and worldwide
regulations
o Communication Protocols
o Network Range
o Network Topology
o Standards and interoperability

13. Frequency bands and
worldwide regulations
▸Can’t be limited to single
frequency
▸Common frequency
2.4 GHz

14. Communication Protocols
Link
• Convert bits to radio
signals
Network
• Routes the data
Transport
• Arranges the sessions
Application
• End user controllability

15. Network range & Topology

16. Standards & interoperability
