A mobile ad-hoc network (MANETs) is an infrastructure less network in which the mobile nodes communicate with each other. Due to its various characteristics like highly dynamic topology and limited battery power of the nodes, routing is one of the key issue. Also, it is not possible to give a significant amount of power to the mobile nodes of ad-hoc networks. Because of all this the energy consumption is also an important issue. Due to limited battery power, some other issues like if some node gets fail, which results in loss of data packets and no reliable data transfer has been raised. In this paper, an algorithm is proposed for data transmission which detects the node failure (due to energy) before it actually happens. Because of this network lifetime gets improved. The proposed routing algorithm is energy efficient as compared to AODV routing algorithm. The performance is analyzed on the basis of various performance metrics like Energy Consumption, Packet Delivery Ratio, Network Life Time, Network Routing Overhead and number of Exhausted nodes in the network by using the NS2 Simulator.
