Abstract

Topology control with per-node transmission power adjustment in wireless ad hoc networks has been shown to be effective with respect to prolonging network lifetime and increasing network capacity. In this paper, we propose a fully distributed, asynchronous and localized energy-saving topology control algorithm for heterogeneous ad hoc networks with non-uniform transmission ranges. We prove the topology derived from the algorithm preserves the network connectivity and bi-directionality. It need not the position system support and dramatically reduces the communication overhead compared to other topology control algorithms. Simulation results show the effectiveness of our proposed algorithm.
