Abstract: Mobile Ad hoc Network (MANET) is self-organizing and self-configuring network that provides mobile users with communication facility and information access regardless of location and any centralized control. The most important characteristic of such networks is the independence of any fixed infrastructure. Therefore, it can be rapid and easily deployed. The typical application of Ad Hoc networks includes battle field communication, emergency relief, information sharing at conference or classroom etc. Routing is one of the important issues in MANETs due to their highly dynamic and distributed nature. Also nodes in MANET are usually battery powered. Draining out of a node can partition the network and result into reduced packet delivery and network lifetime. In this paper one of the existing protocols is selected and modified to make it energy efficient. The modified algorithm tries to increase network lifetime by implementing few modifications to basic DSR protocol. Remaining node energy is used to implement energy conservation. It is observed from the simulations that this algorithm improves network lifetime of MANETs.
