Collision aware topology control algorithm in wireless multihop networks

Abstract

Energy conservation and interference reduction are the two main goals of any topology control algorithm in wireless multi-hop networks, but impacts of traffic on interference have been largely ignored in almost all previous works. In this paper, we showed that traffic load has significant influence on energy consumption of network nodes and then we made a relation between traffic and interference using collision numbers. Then, we presented a distributed algorithm on topology control to address this challenge by considering collision numbers as a main factor in selection of links. This algorithm tries to improve initial topology to reduce collision numbers. Simulation results verified superiority of the proposed approach over a number of reported techniques in literature.
