An Energy-Efficient Protocol for Power Conservation in Mobile Ad-hoc Networks

The challenging factors in mobile ad-hoc communication are energy resource; hence energy expended for data transmission across the network has to be minimized. MANETs are constrained by limited power so energy management is to be focused. The challenging factors for energy efficient communication is determining energy efficient communication strategies between source and destination nodes through multi-hop networks. The energy efficient strategies need to consider the best route, power associated with each route and the slots during which the routes are to be chosen. In this paper an efficient energy management protocol E-power is proposed. The objectives are to reduce end-to-end delay, increase packet delivery ratio and throughput. E-power is based on IEEE 802.11 power saving techniques. It is proposed to reduce power consumption and reduce transmission latency on useless tasks. The simulations have been done by changing the initial energy, transmission power and receiving power level parameters using NS 2.34 simulators.
