Admission control and packet scheduling mechanisms are used in service differentiation and QoS support. Implementation of these mechanisms in IEEE 802.16 is vendor specific. This paper states the problems and proposes solutions for admission control and packet scheduling in IEEE 802.16 networks. The proposed algorithms will enhance bandwidth utilization and guarantee QoS for different types of service. The authors consider bandwidth polling overhead incurred by services being requested and fair in resource allocation. The IEEE 802.16 Standard for WiMax defines architecture with a Base Station (BS) and a number of Subscriber Stations (SSs). Point-to-Multi-Point (PMP) and Mesh modes are defined in the standard.
