Expected residual lifetime based ad hoc on-demand multipath routing protocol (ERL-AOMDV) in mobile ad hoc networks

Abstract

Nodes in ad hoc networks have limited battery power. So, it is crucial to save energy in this kind of networks. Among various multipath protocols, Ad hoc On-demand Multipath Distance Vector (AOMDV) routing algorithm is a standard one. Among the recent advancements to AOMDV, MMRE-AOMDV (Minimal Maximal Nodal Residual Energy—AOMDV) is state-of-the-art from the perspective of energy efficiency. In this article, we propose ERL-AOMDV which investigates deeper than residual energy of nodes. What it emphasizes is that expected residual lifetime of nodes and approximate completion time of a communication session are important to elect optimum routes. First three optimum routes are used for transferring data packets. Simulations results show that ERL-AOMDV performs significantly better than ordinary AOMDV and MMRE-AOMDV.
