There are several challenges while designing a routing protocol for MANET due to the limited energy, less processing capability, fewer resources and dynamic environmental changes. Most of the existing energy efficient protocols focuses on choosing a route or path through the nodes with maximum residual energy and distribute a network traffic blindly among generated paths. Network congestion caused due to traffic and node packet carrying capability based on its remaining energy are not considered which leads to increasing number of dead nodes and result in more energy depletion. Hence we have proposed a Power Aware Load Balancing Multipath Routing Protocol (PALBMRP) which selects an optimal energy efficient route based on multiple parameters i.e. residual energy, delay, congestion and hop count and perform load balancing by considering nodes minimal residual energy to transmit packets according to its capacity. The simulation shows the proposed protocol reduced overall energy consumption up to 9%, increased packet delivery ratio up to 12%, and reduced end to end delay up to 3%, compared to AOMDV and LBMMRE-AOMDV [1].
