Mobile Ad Hoc Network (MANET) routing is challenged by power and bandwidth constraints as well as frequent topology changes to which it must adapt to and converge quickly. Energy efficient routing protocols play an important role in MANET. This paper presents an innova- tive energy aware routing protocol for wireless ad hoc net- work called Energy Efficient Ad hoc On Demand Multipath Distance Vector (E 2 AOMDV) routing protocol. Ad hoc On Demand Multipath Distance Vector (AOMDV) routing pro- tocol presents the advantage of achieving faster and efficient recovery from node failures. We propose the inclusion of Energy Aware (EA) selection mechanism and the maximal nodal surplus energy estimation in the AOMDV routing protocol to improve its energy performance in mobile ad hoc networks. The 'readiness' concept of EA Selection me- chanism prolongs the network lifetime and the maximal nodal surplus energy estimation concept increases the ener- gy efficiency of E 2 AOMDV routing protocol. A comparison of E 2 AOMDV and AOMDV routing protocols can be done using the performance metrics like packet delivery ratio and network lifetime to show that the former outperforms the latter and confirms to be a better performing routing proto- col in saving battery energy in a dense mobile network with high traffic loads.
