Improving Energy Efficiency of MANET by Enhanced Distance Based Broadcasting Protocol
K. Sangeetha Supriya, P. Subbaiah, V. Ramesh · 2013
Mobile Ad-Hoc Network (MANET) is wireless networks consisting of a collection of mobile nodes with no fixed infrastructure, where some intermediate nodes should participate in forwarding data packets. Energy conservation is a critical issue in ad hoc wireless networks for node and network life. Enhanced Medium Access control (eMAC) protocol prevents link/routing failures, hidden/exposed terminal problems and broadcast storm problems using an adaptive unreachability reporting mechanism with more energy consumption. Furthermore, An adaptive table broadcasting technique is proposed to facilitate topology information dissemination in mobile ad hoc networks (MANETs). In this paper, a cross layer design for enhancing the distance based broadcasting protocol is proposed in terms of energy consumption. Instead of using the distance, the reception signal strength is considered. The necessary transmission power to reach an intended device is obtained using the beacons.If the furthest node can be reached using less power than the default value, the transmission power is reduced and it saves energy. Different proposals for enhancing the algorithm are proposed, and they not only save energy but also highly reduce the number of collisions. Keywords - Energy efficiency, Mobile Ad-hoc Networks, cross layer design, unreachability, and distance based broadcasting.
