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

Smart Grid-ZigBee
  • 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

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

8
Smart Grid-6LoWPAN
  • 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.

9
ZigBee/6LoWPAN
10
Problem
  • There is still no universal network management
    protocol standard to manage two different types
    of ZigBee and 6LoWPAN devices.
  • This paper proposed Session Initiation Protocol
    (SIP) application layer protocol to manage
    ZigBee and 6LoWPAN WSNs.

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

12
System Architecture
  • IPv6 and SIP are added to the Smart Grid
    management system.
  • Smart Grid
  • ZigBee-based
  • 6LoWPAN-based
  • Hybrid
  • SIP network management module

16
SIP network management module
Instant Message
Subscribe / Notify
17
Subscribe and Notify Module
  • Servers can subscribe data which it wants to
    monitor from end devices.
  • Example
  • Electricity consumption
  • Temperature of meter

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

19
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.

20
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.
