Energy-Efficient Routing in MANET Using Load Energy Metric

A mobile ad hoc network (MANET) is a collection of mobile nodes that are ceaselessly self-designing and work on foundation-less network. A mechanism for broadcasting is flooding where a request is retransmitted by a node at least once, but it is ineffectual in terms of bandwidth and energy. Energy management plays an important role in network. The proposed scheme uses two techniques: First technique is calculating queue length of every node to reduce normalized routing load. The second technique is selecting the route based on a threshold value to maintain efficient transmission to destination. The proposed protocol uses load energy metric algorithm which conserves the energy levels of nodes. The algorithm considers the queue length of every node. The work is implemented using ns2 simulator. The performance evaluation shows a reduction in routing overhead when compared to existing approach and AODV routing protocol.
