A Broadcasting Method considering Battery Lifetime and Distance between Nodes in MANET

This paper proposes a broadcasting method considering the residual battery lifetime of each node and distance between relay nodes in MANET (mobile ad-hoc networks). In the method, broadcasting packets are sent with high reachability, low network load and low broadcasting latency to a whole network. So far, many broadcasting methods have been proposed. But, since most methods do not take into consideration the residual battery lifetime of each node, there is a possibility that reachability decreases with time lapse. As a method which considers the residual battery lifetime of each node, FBC (fair battery consumption) has been proposed. However, there is a possibility that the number of dead nodes rapidly increases because the difference between the residual battery lifetimes of each node decreases with time lapse. By simulation, the proposed method is compared with existing methods and the effectiveness of the proposed method was confirmed.
