Dynamic Power Allocation in Wireless Routing Protocols

Power optimization in routing Protocol is an important factor in a mobile ad hoc network. In all of the existing routing protocols when a packet travels from source to destination, then source and all the intermediate nodes in the path assign a constant energy to the packet irrespective of the distance packet has to travel and hence there is wastage of power. In this paper, a new power control mechanism has been proposed which find the distance between two nodes, calculate the power required to cover the distance and assign only that amount of power to the packet. This mechanism works at physical layer, so this can be used with any of the existing routing protocols. After deployment of the scenario in a simulator, simulation result will show that energy consumption by using the proposed technique is less than the traditional mechanism used in the protocols.
