The multiagent system for channel selection and topology control on 802.11 based mesh networks

Abstract

To address the problem of topology control on multi-radio wireless mesh networks a distributed, lightweight, co-operative multiagent system that guarantees scalability has been developed and validated by simulation. Our goal is twofold, to select channels so to reduce interference, and improve connectivity by shortening paths between portal and client nodes. As this system is to be deployed over large networks the scalability and stability of the solution are of the main concern. The proposed algorithms have been implemented and evaluated with the Java based framework as well as NetLogo a multiagent simulation tool. The positive attributes of the algorithms are demonstrated through the comprehensive simulation result analysis. © 2008 Springer-Verlag Berlin Heidelberg.
