A mixed approach load balancing and efficient energy for multi-path routing in mobile ad hoc networks

Load balancing and energy efficient are recognized as a crucial issue in ad hoc networks. Several routing protocols have been proposed in order either to distribute equitably the workload among the nodes of network or to consume in efficient way the residual energy of nodes. In this paper, a novel approach is proposed to enhance the AODV routing protocol by considering the node capacity for relaying the data packets to the destination. The node capacity considers both the workload and remaining energy of node. Using these criteria, a modified AODV protocol is proposed AODV-LB which improves the packets delivery ratio and prolongs the network lifetime. Simulation shows that AODV-LB surpass the AODV and the protocol Energy Efficient Ad-hoc on Demand Vector (E²AODV) by reducing the consumed energy and the packets loss ratio in the network.
