Wireless Mesh Network (WMN) is considered to be an effective solution to support multimedia services in last miles due to their automatic configuration and low cost deployment. The main feature of WMNs is multi-hope communications which may result in increased region coverage, better robustuess and more capacity. Implemented on limited radio range wireless media, WMNs bring about many challenges such as fading alleviation, effective media access control, efficient routing, quality of service provisioning, call admission control and scheduling. In this paper main concepts of scheduling in mesh networks are introduced and its basic techniques in WMNs are reviewed.
