In large-scale IoT deployment there will be rich combination of sensors and intelligent management schemes. Wireless sensor networks (WSNs) play a very
important role in IoT.
WSNs are adopted in many applications. This paper focus on the application of Smart Grid.

IPNetwork
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
ZigBee Based on IEEE 802.15.4 Network layer and application layer

ZigBee
Local network and InternetZigBee devices can communication to each
other.ZigBee devices can not directly communicate
with servers on the Internet.An additional mechanism is required to
translate ZigBee to TCP/IP. It would be better if have protocol can speak
with TCP/IP without translation.

6LoWPAN ( IPv6 over Low-Power Wireless Personal Area Networks) Based on IEEE 802.15.4 Network layer – IPv6
Compatible with Internet Do not need additional protocol translation.
6LoWPAN
8
There is still no universal network management protocol standard to manage two different types of ZigBee and 6LoWPAN devices.
This paper proposed using SIP(Session Initiation Protocol ) as the application layer protocol to manage ZigBee and 6LoWPAN WSNs.

Subscribe and Notify Module

Servers can subscribe data which it wants to monitor from end devices.
Example:Electricity consumption Temperature of meter
Instant Message Module
19
Servers can send commands to devices.
Example:Shutting down or
starting devicesChanging devices

This paper compared the communication protocols between a utility system and smart meters, and suggested how network management applications can be carried on these protocols.
Two major network management protocols: SNMP(Simple Network Management Protocol)and SIP.

Conclusion and future work
Empirically 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.
