Distributed fault tolerant topology control in wireless ad-hoc sensor networks

Abstract

Topology control is an important problem in wireless ad-hoc sensor networks. The aim of the topology control is to maintain desired properties of the network topology to improve the performance of networking algorithms (e.g. routing). In this paper, we present a distributed algorithm for assigning minimum possible power to all the nodes in the wireless sensor networks, such that the network is K-connected. Extensive simulation has been performed to prove the optimality of the algorithm
