Network Life Time maximization of the AOMDV Protocol Using Nodes Energy Variation

Mobile ad hoc network presents generally several challenges such as high dynamic topology, packet loss and frequent routes discovering that result in low throughput and reduced packet delivery ratio. To reduce the number of route discovering process, multipath routing protocols makes use of alternate paths to continue packets transmission. Ad Hoc On-demand, multipath distance vector routing protocol or AOMDV, is one of the well-known multipath protocols that relays on the hop count metric to route packets. However maintaining disjoint active routes can reduce nodes life time and lead to more control messages like error and discovering packets. In this paper, a pre-emptive approach is proposed based on the historical values of nodes energy. Nodes that excessively consume energy in time are considered overloaded and are excluded from route discovering, hence nodes with reduced energy variation are selected to route packets. Simulation results show reduced number of dead nodes by 30 %, overhead by 16%.
