This chapter presents some performance issues in Worldwide Interoperability for Microwave Access (WiMAX) network and focus on the capability of non-transparent relay in Mobile Multi-Hop Relay (MMR) WiMAX Network. In this work, an admission control mechanism with hierarchy Quality of Service (QoS) is developed for the relay architecture. An open source-based simulator is used to evaluate the three types of QoS classes, which are Unsolicited Grant Access (UGS), Real Time Polling Service (rtPS), and Non-Real Time Polling Service (nrtPS). Two scenarios of non-transparent relay topologies are set up for different numbers of subscribers with different types of QoS application classes. Three performance metrics, which are bandwidth utilization, number of slots used, and number of admitted service flow, are observed and plotted in graph. The results show the hierarchy-based QoS admission control mechanism can enhance the throughput of provided services by 35% compared to the conventional method without the admission control approach.
