IEEE 802.16 (WiMax) technology is designed to support broadband speeds over wireless networks for the coming era of Broadband Wireless Access (BWA). IEEE 802.16 is expected to provide transmission of high-rate and high-volume multimedia data streams for fixed and mobile applications. As an extension of Point-to-Multipoint (PMP) configuration, the IEEE 802.16 mesh mode provides a quicker and more flexible approach for network deployment. Multimedia networking requires Quality-of-Service (QoS) support, which demands elaborate mechanisms in addition to the four service types defined in the specification. By examining standard centralized and distributed scheduling/routing schemes in the mesh mode from QoS aspect, a BS-controlled and delay-sensitive scheduling/routing scheme is proposed in the paper.
