Performance Improvement of Energy-Aware MANET Routing Algorithm Using Load-Balancing

Most research on energy-aware routings in mobile ad hoc networks (MANETs) only focuses on minimizing the total energy consumption from the source node to the destination node, regardless of the performance degradation caused by the heavy traffic load in the network. In this paper, we propose an energy-aware load-balanced routing (EALB) algorithm. Simulation results demonstrate that the proposed routing algorithm significantly increases the packet delivery ratio, reduces the delay and prolongs the network lifetime in heavy load networks. EALB can also provide better performance when nodes have very low energy levels.
