Wireless mesh networking is becoming an economical means to provide ubiquitous Internet connectivity. In this chapter, we study wireless communications over multi-radio and multi-channel wireless mesh networks with IEEE 802.11e based ingress access points for local clients and point-to-point wireless links over non-overlapping channels for wireless mesh network backbones. We provide a set of algorithms to analyze the performance of such wireless mesh networks with wideband fading channels in various office building and open space environments and commonly-used Regulated and Markov On-Off traffic sources. Our goal is to establish a theoretical framework to predict the probabilistic end-to-end delay bounds for real-time applications over such wireless mesh networks.

The IEEE 802.11e standard is mostly concerned with traffic differentiation in single-hop infrastructured wireless networks. Wireless mesh networks use several wireless hops in order to forward packets to their destination. A significant issue is that the standard does not map network characteristics into the access protocol parameters it provides. This paper investigates different configurations of the IEEE 802.11e access parameters in wireless mesh networks and proposes two configuration settings. Both proposals provide voice traffic service guarantee without significantly degrading the performance of other multimedia traffic classes, as demonstrated by simulation experiment results.
