Abstract:
This paper proposes a concept of neighbour congestion table,improves Ad Hoc on Demand Distance Vector(AODV) Protocol on the base of bypass,neighbour congestion table,hello message and Next Green-hop Requset(NGRQ) systems.A routing protocol of congestion adaptive Ad Hoc on demand distance vector(CA-AODV) is proposed.In CA-AODV protocol,a primary node can be aware of network congestion immediately by using neighbour congestion table.When congestion happens,the previous node of congested node on the primary route can discover a bypass on-demand to bypass the congestion node.When data flow gets to the node with a bypass,they are distributed in primary path and bypass proportionally.As a result,it can realize the congestion adaptive function.The simulation results show that the CA-AODV protocol can obtain less delay from the average end to end,higher data delivery ratio,less normalized overhead as compared to AODV.
