Energy Conservation by Improving Flooding Mechanism in MANET

摘要

Ad hoc On-demand Distance Vector (AODV) is the most widely used routing protocol in mobile ad hoc network where every node broadcasts control packets with unit rebroadcast probability causing too many redundant transmissions leading to unnecessary energy consumption and hence reduced network lifetime. The limited power of the mobile devices is always a concern for research community forcing to develop more and more energy efficient techniques and protocols to increase the service lifetime. This paper proposes a fixed probabilistic based energy efficient route discovery method for mobile ad hoc networks (MANET) which is imbibed in traditional AODV protocol to give its enhanced version termed as FPAODV. The novelty in proposed FPAODV protocol is the analytical method along with algorithmic approach developed to determine the threshold rebroadcast probability is more generic and efficient. This probability at each node decides the rebroadcasting of received control packets to its neighbours. It is demonstrated that the proposed protocol outperforms the existing routing protocols from their class in terms of average received control packets per node and the energy consumption.
