Energy-aware reliable routing by considering current residual condition of nodes in MANETs

Abstract

Mobile ad hoc network design’s goal is to provide Internet connectivity anywhere and anytime regardless of geographical location. Application of MANET includes disaster recovery, military, and environment monitoring. Resource-constrained environment of MANET makes its communication operations very much challenging. Moreover, network nodes are equipped with constrained batteries and it is much tough to replace or recharge the batteries during the mission. Thus, MANET requires an energy-efficient mechanism to address the constraints. We are achieving the energy efficiency through network layer, as MANET is infrastructureless peer-to-peer network. We develop a new reactive energy-efficient routing protocol based on knapsack mechanism. It selects the routing path based on the current residual condition of network nodes. Simulation results conclude that our proposed method is better in comparison with the existing works E-AODV, MRPC with respect to network lifetime and link stability.
