Abstract


In order to support multiple types of service with different QoS requirements in heterogeneous wireless networks, efficient resource management, call admission control (CAC) strategies, and mobility management are important issues. In this paper, we propose the Bandwidth Management Strategy 1 (BMS1), Bandwidth Management Strategy 2 (BMS2) and reservation scheme with Fuzzy controller for improving CRP (call rejection probability) of real-time services. Simulation result shows that the proposed methods outperform our previous work under real-time services, such as UGS, rtPS and ertPS.
