Abstract
In ad hoc networks, the battery-based power is a precious resource. Maximizing the network lifetime becomes a challenge issue in MANETs when energy is limited/finite. In this paper, we propose a new mechanism to prolong network lifetime. Our approach, based on Relative Neighborhood Graph (RNG), performs transmission range modifications to manage the node degree based on local information. It is our goal that each node can extend its lifetime to maintain the connection of the whole network. By managing the node degree, we can reduce collision in ad hoc networks. Then we can achieve the goal of power saving. Our new mechanism provides appropriate transmission power range to routing protocols such as AODV, DSR and BELLMAN-FORD. Simulation results show that better improvement in energy saving for routing protocols can be obtained as compared with those without our mechanism.
