Weighted QoS admission control for IEEE 802.16j WiMAX networks

Abstract

Scheduler is one of the crucial mechanisms that influence the delivery of quality of services in WiMAX (Worldwide Interoperability for Microwave Access) networks. With the rapid advances in telecommunication technologies, Mobile Multi-hop Relay (MMR) WiMAX is introduced to satisfy the ever increasing demand for higher speed and throughput. This paper discusses the scheduling technique specifically for the admission control of real-time Polling Service (rtPS). The simulation studies were conducted by adopting the weighted QoS method from the NCTUns module. The result shows the proposed admission control is capable to increase the number of subscriber being served and minimize the radio resources wastage. The capability of the admission control was also evaluated for various number of mobile stations deployed.
