The nodes in required battery power for communication and it is very crucial matter to utilize the battery power of nodes efficiently in network. The battery replacement and charging is not possible in that kind of network and the insufficient battery lifetime imposes a limitation on the network performance. To take full utilization of the lifetime of nodes, traffic should be routed in a way that energy consumption is minimized. The energy efficient routing is improves the battery life and routing capability of nodes. In this research we proposed a new energy efficient routing scheme with AODV routing protocol to improve the reliability of data delivery and energy utilization. The proposed scheme is efficiently utilizes the energy of mobile nodes through variation in the energy of nodes on the basis of their radio range in network utilization. It means the nodes are only communicate to nearest neighbor by that the less amount of transmission and receiving energy is required for communication. In this approach the proposer energy utilization and consumption is possible that reduces the improper energy depletion of mobile nodes. The routing performance is measured through performance matrices and the proposed scheme is showing the much better performance as compare to normal energy routing with AODV routing protocol.

INTRODUCTION The Mobile Ad hoc Network (MANET) is an independent network established connection and deliver data in network without any supervision of any authority. Mobile ad hoc networks have various civilian and military applications which have drawn considerable attentions in modern area. The major concerns in designing Mobile Ad hoc Networks is to reduce the energy consumption as the wireless nodes are often powered by batteries only. For a sender to send data packets to a destination that is not in its direct radio range of transmission, the packets must be spread through one or more intermediate nodes [1, 2]. Ad hoc network nodes in most portable devices, limited by the size of the battery-powered, the whole network is an energy-bounded systems, to save the energy of nodes as much as possible and to maximize the total battery life of a wireless network [3] we must minimize the energy consumption of the entire network using intermediate node minimum energy consumption base. This is particularly important in emergency rescue, military operations, business meetings and other situations. From this perspective, the shortest route is not necessarily the best route. On the contrary, with some short hop configurations to replace the relatively long jump configurations may be better energy-saving choices available [4]. At present, there are two main ideas of energy-saving routing algorithms for Ad hoc routing protocols [5]. The first one is to send each packet with minimum energy-consuming. The second is to maximize the network lifetime as much as possible. These two ideas are considered relatively independent of one another, the intention is to combine these two ideas, and to therefore maximize the network’s lifetime and minimize energy consumption. 2. RELATED WORK In this section we study about existing energy aware routing and its benefits, that related work encourage to work the newer research in the field of energy issue in MANET and solve the problem occur on existing system. Sheetal Sisodia et al. [1] in this work comparing two different protocols in context of energy conservation and routing overhead. The proposed work is done in two modules named Node Energy Aware Methodology which includes conditional Min-Max Battery Cost Routing Algorithm (CMM-BCR) and Destination Estimation Module which includes Distance Routing Effect Algorithm for Mobility (DREAM) location based protocol. These two modules together applied over On- Demand Routing protocol which is a Dynamic Source Routing protocol (DSR) and over Destination Sequence Distance Vector Routing Protocol (DSDV) which is a Table driven routing protocol. Simulation shows that when this energy scheme used with DSR provides better result than DSDV. As energy is of main concern in ad-hoc networks so our main aim is to know which among these two protocols is good in energy conservation and increases network lifetime by reducing overhead. Mr. Varun Mishra et. al. has proposed [6] a “Energy Aware and Multipath base Reliable Communication in MANET” in this mechanism they propose a multi-path MAX energy based routing scheme that reduces the congestion and improves the energy efficiency and the reliability in data delivery. In this mechanism the multipath routing protocol reduces the possibility of congestion by using the concept of dynamic queue and MAX energy based routing always selecting the node for routing that has maximum energy. Every data packet is delivered to the neighbour by one or more multiple paths according to their proposed scheme. The stability among multiple paths that considers the energy usage at neighbours is further considered in path selection, which leads to competent utilization of the spread nodes and prevents early death of
