Energy Efficient Routing with Transmission Power Control based Biobjective Path Selection Model for Mobile Ad-hoc Network

The main aim of this paper is to find an optimal path to prolong the network lifetime and to find energy efficient routes for MANET. Routing involves path discovery based on Received Signal Strength (RSS) and residual energy and selection based on an optimized biobjective model. Biobjective here represents energy and hop. In path discovery process, initially, transmit power required is varied to reduce energy consumption. Then the RSS of the Route Request (RREQ) and node's remaining energy are validated for deciding whether a node can forward the RREQ or not. Selecting the path that consumes less energy and less number of hops extends the network lifetime. Theoretical computation is compared with the simulation results. As far as the simulation is concerned, the results of the proposed model called Energy Efficient Biobjective Path Selection (EE-BPS) are encouraging. The selection process fetches us the energy saving, because of this model. On the other hand, if the optimal path is not considered, the nodes will drain off soon and the network lifetime will decrease.
