Abstract

A single-channel wireless mesh backbone may suffer from capacity limitations since all the wireless routers share the same channel. A multi-channel broadband wireless mesh backbone may have different capacity. This paper addresses the problem of channel assignment (CA) with differentiated services (DiffServ) to support the quality-of-service (QoS) in the wireless mesh backbone. We propose a novel, simple and yet highly effective enhancement to the Spanning Tree protocol of ‘hyacinth’ to achieve high degree of QoS by keeping in perspective the different characteristics of the various traffic types in the Diffserv framework. We discuss the problems of CA and present in detail our proposed extension to overcome them
