Increasing Energy Efficiency of Mobile Nodes Using Distributed Energy-Adaptive Location Based Cooperative- Medium Access Control Protocol (DEL-CMAC) in Large Scale MANETs

Abstract

In Mobile ad hoc networks (MANETs), energy plays a major role in transmissions of packets in cooperative communication systems. The cooperative communications enhances the neighbouring nodes to relay the messages from source to destination for obtaining the diversity gains. In order to improve the computing process of mobile nodes in MANETs, the energy needed to transmit the packets plays an important role. In this paper, the Distributed Energy-adaptive Location-based Cooperative Medium Access Control protocol (DEL-CMAC) is proposed to optimize the node’s energy efficiency in MANETs. This proposed DEL-CMAC protocol increases the energy of the node efficiently to transmit the packets and increases the entire network lifetime. In this system, a distributed effective relay selection approach is incorporated for relaying the packets at its best. In addition to this, an innovative Network Allocation Vector (NAV) setting is adapted with this proposed scheme to deal the varying transmitting power of the source and relay nodes. This proposed protocol, increases the nodes’ lifetime significantly with the high circuitry energy consumption when large numbers of nodes are participating the cooperative communication in MANETs.
