Abstract:
The coexistence of different cellular networks in the same area necessitates joint radio resource management for enhanced QoS provisioning and efficient radio resource utilization. It has been proposed adaptive bandwidth management and joint call admission control (JCAC) scheme for heterogeneous cellular networks. The main goal of this research is to evaluate a proposed admission control algorithms in providing QoS . Two call admission controls are compared AJCAC and NAJCAC and we investigates performance metrics new call blocking probability, handoff call dropping probability, delay and throughput. MATLAB is used for the evaluation of algorithms. Simulation results shows higher connection admission rate with AJCAC. The results shows that as the number of user increase the rejection probability in both algorithms. Moreover, the result shows that the connection level of QoS can be significantly improved by using the AJCAC scheme
