A novel energy efficient obstacle aware routing algorithm for MANET

Abstract

In Mobile Adhoc Network (MANET), all nodes are energy and mobility constrained. The presence of obstacles in MANET severely degrades the efficiency of routing protocols in MANETs and consumes more energy for searching new routes. The high energy consumption of wireless nodes makes the MANET routing unpredictable. Therefore, it is important to consider the presence of obstacles in the network while evaluating the performance of the MANET. In this work, we have developed an Energy Efficient and Obstacle Aware Routing Algorithm (EEOARA) for MANET. For obstacles avoidance, the concept of Bezier curve based on DeCasteljau algorithm is used. In the proposed algorithm, to increase the availability of routes and to reduce the number of non-participating nodes, minimum energy consuming path which has maximum residual energy is preferred and selected. The performance of MANET is evaluated using NS2 simulator. Simulation results show that the proposed EEOARA reduces energy consumption, network overhead, delay and increases data delivery in the network.
