Probabilistic Average Energy Flooding to Maximize Lifetime of Mobile Ad Hoc Networks

Wireless mobile ad hoc stations have limited battery capacity, hence, ad hoc routing protocols ought to be energy conservative. Route discovery is a common operation in routing to resolve many issues. In a mobile ad hoc network (MANET) in particular, due to host mobility, such operations are expected to be executed more frequently. A straightforward broadcasting by flooding is usually very costly and will result in serious redundancy, contention, and collision, resulting in broadcast storm problem. In this paper, an algorithm is proposed to improve flooding performance of ad hoc on-demand distance vector (AODV) routing protocol called, probabilistic-average-energy- flooding (PAEF) which periodically performs an averaging algorithm calculate-average-energy (CAE) to estimate the average energy E _avg. This algorithm is used in route discovery process to make a rebroadcast decision by the node. Our simulation results show an improvement in the network lifetime and the throughput compared to traditional AODV.
