Presentation Transcript

  1. AODV-CE AODV clustering extension

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

  3. AODV review

  4. 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

  7. S wants to communicate with D

  8. S sends route request to Smart nodes

  9. J broadcast route request in his neighborhood(TTL=1)

  10. D replies response which is forwarded backward to S

  11. groups

  12. Linux netfilter Ipq Proc filesystem Unix network programming API POSIX Techiques

  13. modules

  14. kernel space Linux TCP/IP statck Route lost Kernel module Linux TCP/IP stack AODV-CE routing Protocl stack kernel routing table manipulation Route query User space Route reply Data Flow
