Abstract:

Route flapping is common in mobile Ad hoc networks.It usually causes large delay or even interruption during communication.This paper proposed a routing protocol AODV-RM to alleviate this effect.AODV-RM selects routes with the lightest traffic load,to avoid striving for hot nodes with other users,hence minishes the chance of collision.AODV-RM keeps all valid routes to the destination in its routing table as backups.When the link under usage breaks down,AODV-RM shifts to a valid route in its routing table instead of route repair or researching,which ensures the continuity of communication.AODV-RM chooses a route maintenance scheme by the network topology.If the origination has multi routes to the destination,only the origination maintains routes.Otherwise,middle nodes,instead of the origination,maintain sub-routes to the destination.By simulating the traditional AODV and AODV-RM,the results showed that AODV-RM has a lower drop rate and better performance against route flapping.

Key words: route flapping route maintenance routing protocol Ad hoc network
