Interference-Aware Channel Assignment in Wireless Mesh Networks
DED ABSTRACT The increased popularity and the growth in the number of deployed IEEE 802.11 Access Points (APs) have raised the opportunity to merge together various disjointed wireless LANs to form a unique wireless mesh network (WMN). In this architecture only few nodes, called Portals (MPPs), interface to the external world thanks to their bridging/gateway functions, while several Mesh Points (MPs) form a wireless backbone acting as relay nodes. But MPs are also able to provide network access to user devices (stations) that are inside their coverage range (thus becoming Mesh Access Points, MAPs). As a result, WMNs are supposed to handle a large amount of traffic, including flows that demand specific requirements, such as VoIP calls or multimedia broadcasting. To this end, one serious limit of 802.11-based WMNs is the fact that the standard plans to use the CSMA/CA access protocol over a single frequency/channel [1]. In the Mesh architecture, where the MPs shall transmit their traffic...
