The IEEE 802.16 or WiMax standard enables deployment of broadband wireless networks in geographically large areas. It supports three modes: Point To Point (P2P), Point to Multi-Point (PMP) and Mesh. WiMax system provides QoS guarantee in terms of bandwidth, delay and jitter. So scheduling and Call Admission Control (CAC) play an important role in a WiMax system. But the IEEE 802.16 standard does not specify any scheduling or admission control mechanism. In this paper, the authors present an efficient centralized scheduling scheme and a QoS aware CAC for WiMax network with a mesh topology.
