Hierarchical QoS admission control mechanism for non-transparent relay in WiMAX networks

This paper presents the admission control mechanism which can minimise the overwhelming effect of limited radio resources as the demand for network service increases. The simulation study was conducted using NCTUns module with hierarchical Quality of Service (QoS) priority method. The result shows the proposed admission control mechanism is able to increase the number of subscriber being served and reduces the radio resources wastage by about 35%.
