DOI: 10.1155/WCN.2005.635Wireless ad hoc sensor networks differ from wireless ad hoc networks from the following perspectives: low energy, lightweight
routing protocols, and adaptive communication patterns. This paper proposes an energy-aware routing protocol (EARP) suitable
for ad hoc wireless sensor networks and presents an analysis for its energy consumption in various phases of route discovery and
maintenance. Based on the energy consumption associated with route request processing, EARP advocates the minimization of
route requests by allocating dynamic route expiry times. This paper introduces a unique mechanism for estimation of route expiry
time based on the probability of route validity, which is a function of time, number of hops, and mobility parameters. In contrast
to AODV, EARP reduces the repeated flooding of route requests by maintaining valid routes for longer durations.Peer reviewe
