A Hybrid Cac Scheme for Effective Resource Allocation in IEEE 802.16 Wireless Networks

Call Admission Control (CAC) plays a vital role in providing the desired Quality of Service (QoS) in broadband wireless networks. The aim of this paper is to propose an efficient Greedy Shaper based Call Admission Control (GSCAC) scheme for WiMAX networks to manage the number of admitted user connections and maximize the utilization of the wireless resources. The proposed algorithm is based on bandwidth reservation and greedy shaper concepts. It has been developed considering the problem of \"Busy hour\" in communications traffic variation during a typical day. The success of the proposed scheme depends on the revenue it generates to the service providers and service quality it provides to its subscribers.
