Abstract

Wireless Mobile Ad-hoc networks are very popular for their dynamic, infrastructure less and decentralized configuration capability with battery powered nodes. Routing in such networks is a key issue which decides network performance. AODV protocol is one of the reactive routing protocols in MANET used for various network conditions like sparse and dense network with different speeds of mobile nodes. Sometimes due to unbalanced node usage, some of the battery powered nodes drains out faster. This leads to route re-discovery causing larger average end to end delay and more control overhead. In this paper we are presenting Energy Factor based AODV (EFAODV) protocol, efficient modification to existing AODV protocol to take care of this problem for different network situations. The QualNet simulator is used for comparison of AODV and modified EFAODV protocol. There is significant decrease in average end to end delay and control overhead using EFAODV protocol while maintaining the other quality of service parameters useful for highly mobile network
