Energy Conservation in Mobile Ad-Hoc Network using Enhanced Fitness Function

In MANET, a collection of mobile nodes forms a wireless network. MANET forms a temporary network without the aid of any fixed infrastructure or centralized administration. A MANET is referred as an infrastructure-less network. The mobile nodes in this network dynamically sets up paths among themselves to transmit packets temporarily. Though MANET possess attractive advantages, it faces some challenges due to their particular characteristics. One of the important challenges is the limited energy resource, as the mobile nodes do not possess permanent power supply and have to rely on batteries. It reduces the network lifetime as batteries get exhausted very quickly as nodes involves the transmitting and receiving of packets and mobility of nodes. In existing system, the energy in MANET is conserved by applying the fitness function technique to optimize the energy consumption in Ad Hoc on Demand Multipath Distance Vector (AOMDV) routing protocol. The protocol used is AOMDV with fitness function (FF-AOMDV). The problem identified is usage of intermediate nodes for forwarding packets is more. It reduces the energy of the nodes. In this paper, the usage of intermediate nodes is reduced based on maximum transmission range by using Enhanced Fitness Function. It conserves the energy of the remaining nodes in the network and increases the lifetime of the network.
