A new energy based power aware routing method for MANETs

A mobile ad-hoc network (MANET) is a self-configuring and self-directed functioning system that operates without infrastructure and rapidly deploys in a network. The MANET does not need centralized administration. It contains a mobile node for wireless transmission and MANETs that can be established anywhere. In addition, any instance of the ad-hoc network is effective since it is capable of eliminating the complexity of central admission and infrastructure. The MANET is widely in use in many fields such as military applications, mobile communication, and emergency situations. Energy consumption is an important issue in MANET because the mobile nodes are battery powered. In this paper, a dynamic energy ad-hoc on-demand distance vector routing protocol (DE-AODV) is proposed to minimize the packet delay, maximize the network lifetime, and reduce the energy consumption. The increase in node energy and dynamic supply of external energy is through a battery. The energy mechanisms consider whether the mobile nodes are in sleep, active, or transmit mode. The DE-AODV protocol is used to find out the selection of nodes which are energy-efficient and trustworthy to select the shortest route path from source to destination. The routing protocols use the external battery when there is a chance of link failure during packet transmission time. The proposed DE-AODV routing protocol provides efficient output when compared with other existing techniques. Simulation results show that the proposed system achieves better performance when compared with previous protocols in terms of packet delivery ratio, network stability rate, end-to-end delay of packets, end-to-end transmission, and throughput.
