Enhancements in AODV routing using mobility aware agents

In infrastructure-less mobile and ad-hoc networks the routes have to be refreshed often due to the mobility of the nodes acting as routers. If a node is aware of the mobility of neighboring nodes, the highly mobile node can be avoided to be the part of routes and ultimately reduces the re-route discoveries. This paper introduces mobility aware agents in ad-hoc network nodes and modifies HELLO packets of the AODV protocol to enhance mobility awareness. Mobility aware agent can update its awareness through inquiry and reply to inquiries about neighbors on quasi-periodic bases. On receiving the HELLO packet with GPS coordinates of the originator, agent compares them with previous ones and hence has awareness about the mobility of the originator with reference to itself. The enhancements in the throughput of the network are studied through simulation in OPNET that has shown optimistic results.
