چکیده
To address the problems of topology control and channel assignment on a multi-radio mesh networks a distributed, lightweight, co-operative multiagent system that guarantees scalability has been developed and validated by simulation. Our overall goal is twofold, to select channels so to reduce interference and improve connectivity by shortening paths between portal and clients nodes. As this system is to be deployed over large networks the scalability and stability of the solution are of the main concern. The algorithms developed have been implemented and evaluated with the help of NetLogo, a multiagent simulation tool. The attributes of the developed algorithms are demonstrated through the comprehensive simulation result analysis.
