AODV-CE

• AODV clustering extension

2
node type

• only one type of node, all the node are equal

AODV review

AODV review(Continued..)

• Traffic flooding to whole network
• Long response time
• Result
• poor scalability
• good reactive routing protoocol suitable for
  smaller network

5
node type

• smart node
• node that sends smart message anouncement
  periodically to the whole network
• ordinary node
• node that play role similiar to AODV network
  node.

6
AODV-Clustering Extension

• Better scalability
• Less traffic flow in route discovery
• Dynamic backbone nodes
• Extendable structure design

S wants to communicate with D
8
S sends route request to Smart nodes
9
J broadcast route request in his
neighborhood(TTL1)
