In Mobile Ad-Hoc Networks (MANETs), mobile devices are operational with power. In order to utilize these energy operational devices resourcefully for transmission of data packets, many energy aware routing strategies are followed. As a key note to these routing strategies, the energy aware performance metrics are analyzed on three routing protocols like Ad-Hoc on Demand Distance Vector Protocol (AODV) , Reverse on Demand Distance Vector Protocol (RAODV) and Destination Sequenced Distance Vector Routing Protocol (DSDV). The comparison results prove that ERAODV protocol can be adopted for any routing strategy, in order to increase the performance of the network lifetime in comparison with RAODV, AODV and DSDV.
