To meet the day to day challenges of wide usage of Mobile Ad hoc Networks (MANETs), energy efficient routing techniques is required to save battery power for a long network lifetime. In this paper, energy efficient Modified Bellman Ford Algorithm (MBFA) is proposed. The performance of a network depends on the node deployment. The network using two node deployment techniques, Grid topology (GT) and Random topology (RT) is implemented using QualNet Simulator. The proposed MBFA finds the shortest path using residual energy (RE) as a metric along with hop count and distance. Nodes in the network operate in Power Save Mode (PSM) using IEEE 802.11a/g Orthogonal Frequency Division Multiplexing (OFDM) standards of the Power Save Mechanism. PSM is energy efficient and improve network lifetime. Generic Radio Energy Model in QualNet Simulator is considered in route energy calculation. The performance of MBFA using fixed network traffic is investigated for both GT and RT. Simulation results show that the performance of GT using PSM is better when compared to RT. The energy consumed by MBFA with PSM is only 35-42% for static networks and 34-48% for mobile networks of MBFA without PSM.
