A novel AODV routing algorithm based on local route maintenance in Tactical MANETs

摘要

Aim at improving the performance and efficiency of AODV protocol in Tactical MANETs which has large scale and fast changing topology, a novel AODV algorithm - LRM-AODV based on local route maintenance is proposed. According to the feature that there always exist many idle nodes, LRM-AODV adopts reverse route search procedure for idle nodes to produce many local routes and increase the route redundancy in the network, this speed up the route discovery and make the fast route repair possible. The simulation results indicate that the performance of LRM-AODV is superior to AODV in packet delivery ratio, end-to-end packet delay and routing overhead.
