Throughput Enhancement in AODV Routing Using Mobility Awareness

In mobile ad-hoc networks routes have to be refreshed frequently due to the mobility of nodes acting as routers to forward data. If a node in a mobile ad hoc network is aware of the mobility of neighboring nodes, a highly mobile node can be avoided to become a part of routes, this will reduce re-route discoveries. A node becomes aware of its neighbors through inquiries and reply to inquiries. These inquires can be quasi-periodic or demand based. This paper focuses on the quasi-periodic inquiries. The HELLO packets of the AODV protocol are modified to achieve it. On receiving a HELLO packet with GPS coordinates of the originator, a node compares them with the previous coordinates and hence becomes aware about the mobility of the originator with reference to itself Mobility awareness in nodes improves throughput of a mobile ad-hoc network
