Energy Efficient Path Formation Approach in Wireless Ad Hoc Network

In wireless ad-hoc network, all nodes work with the predefined limited battery power. It is difficult to select the path from source to destination considering both the parameters i.e. less energy consumption and shortest path at the same time. This paper proposes a novel strategy that approach tries to account for energy efficient path with the minimum number of hops using a priority to check between energy efficient nodes and the path length in the network. It uses math formulation for priority function and algorithm. In order to verify our proposed solution a tradeoff optimization formulation has been designed and a routing protocol called Source to Destination Energy Efficient Path (SDEEP) has been proposed. The routing scheme compares as DSR, EPAR, and LAER. The simulation has done in the well-known network simulator NS-2. The protocol performance is measured in term of packet delivery ratio, end to end delay, nodes lifetime and average energy consumption. The proposed approach outperforms with respect to existing approaches.
