A Probabilistic Method to Optimize Energy Consumption in Mobile Ad-hoc Networks

In Mobile Ad-hoc networks, the rout discovery is accomplished by sending control packets from source node to destination node through intermediate nodes. The replicated copies of the control packets are received at each node of network system. It results in more node energy consumption. In this paper a Threshold probabilistic Route Discovery (THPRD) method has been discussed which helps in reducing the node energy by reducing replicated copies of control packets. The proposed method uses threshold probability which is always less than one in contrast to standard Route Discovery Methods where probability is always unity. The simulation study of the proposed method has resulted in reduction of energy by 40% compared to already existing methods. The simulation study has been carried out for both ad-hoc networks - Grid and Random Scenarios on Network Simulator-2.
