Io. T(cont. ) In large scale Io. T deployment there will be rich combination of sensors and intelligent management schemes. Wireless sensor networks (WSNs) play a very important role in Io. T. WSNs are applied in many fields. This paper focus on the field of Smart Grid. 4

Smart Grid-Zig. Bee IEEE 802. 15. 4 was proposed for wireless personal area network communication. Physical layer and data link layer Characteristics: short distance transmission、low power consumption、low cost Zig. Bee Based on IEEE 802. 15. 4 Network layer and application layer 6

Smart Grid-Zig. Bee(cont. ) Local network and Internet Zig. Bee devices can communicate with each other. Zig. Bee devices can not communicate with servers directly on the Internet. An additional mechanism is required. 7

Smart Grid-6 Lo. WPAN 6 Lo. WPAN（IPv 6 over Low-Power Wireless Personal Area Networks） Based on IEEE 802. 15. 4 Network layer – IPv 6 Compatible with Internet Do not need additional protocol translation. 8

Zig. Bee/6 Lo. WPAN 9

Problem There is still no universal network management protocol standard to manage two different types of Zig. Bee and 6 Lo. WPAN devices. This paper proposed Session Initiation Protocol (SIP) application layer protocol to manage Zig. Bee and 6 Lo. WPAN WSNs. 10

Network management-SIP Control communication protocol Point to point Multiple points Applications Voice over Internet Protocol(Vo. IP) Instant Message Network Management 11

System Architecture IPv 6 and SIP are added to the Smart Grid management system. Smart Grid Zig. Bee-based 6 Lo. WPAN-based Hybrid SIP network management module 12

SIP network management module Subscribe / Notify Instant Message 16

Subscribe and Notify Module Servers can subscribe data which it wants to monitor from end devices. Example: Electricity consumption Temperature of meter 17

Instant Message Module Servers can send commands to devices. Example: Shutting down or starting devices Changing devices settings 18

Conclusion and future work This paper compared the communication protocols between power plants and clients, and suggested how network management applications can be carried on these protocols. Two major network management protocols: SNMP(Simple Network Management Protocol)and SIP. 19

Conclusion and future work (cont. ) Comparing SNMP and SIP, especially analyzing the transmission performance and the system resources consumption on a device. This would allow administrators to manage a smart grid with the best management protocol. 20
