In order to prolong the lifetime of ad hoc networks, it is the most critical issue to optimize the energy consumption of nodes. In this paper, we propose a power aware routing protocol for choosing energy efficient optimum route selection & network approach. This system also considers transmission power of nodes and residual energy as energy metrics in order to maximize the network lifetime and to reduce energy consumption of mobile nodes. The objective of our proposed system is to find an optimal route based on two energy metrics while choosing a route to transfer data packets. This system is implemented by using NS- 2.35. Simulation results show that the proposed routing protocol E-EPAR with transmission power and residual energy control mode can extend the life-span of network and can achieve higher performance when compared to EPAR and DSR routing protocols.

Introduction A MANET (Mobile ad hoc network) is multi-hop wireless network that consists of mobile nodes that communicate via direct path or multi-hop wireless links in the absence of fixed infrastructure. Mobile Ad-hoc network is multi hop wireless network that are communicate between two mobile nodes treated as indistinguishable no matter what is the distance between these nodes. Energy conservation is the most important issues in ad hoc networks The nodes of these networks have several constraints such as limited bandwidth, transmission range and processing capability due to which the network working has to be fully decentralized i.e. message processing or message passing must be done by nodes themselves using certain protocols is to be use in a lot of practical applications, including personal area networks,(PAN) home area networking, military environments, and search a rescue operations. The wide range of applications has led to a recent rise in research work and development activities. Efficient energy conservation plays an important role in the performance of MANET routing because mobile host in such networks are usually battery-operated. Recently, some of energy efficient routings have been proposed, but most of them consider energy conservation in a static or relative static state. This work coordinated considers the stability of link and remaining power of node to be utilized. Each node in MANET utilizes its limited residual battery power for its network operations. Therefore conservation of battery power is a crucial aspect for researchers in MANET. Several researchers even today are working in this direction to conserve battery. Several mechanisms have been proposed to conserve battery power such as utilizing variable transmission range of radios, minimizing the number of hello broadcasts packets. In addition to its research area on conserving battery power using routing schemes is still going on. Various power aware routing protocols that are used for to extending the battery lifetime such as Minimum Total Power Routing Protocol (MTPR), Minimum Battery Cost Routing Protocol [MBCR], Power-Aware
