Abstract:


The quality of service (QoS) is a key element in the communication system; many call admission control algorithms are being used to improve the performance of the system as well as the quality of service. This work represents the effective differences between the Single Cell-Call Admission Control (SC- CAC) and Multi Cell-Call Admission Control (MC-CAC) in mobile communication networks. MATLAB simulation model was implemented to compare between these two CACs in terms of probability of outage and optimal power allocation. The results show that MC-CAC has better performance than the SC-CAC which means minimum values of probability of outage and maximum values of Shannon channel capacity can be achieved by using MC-CAC, and this will improve the quality of service. Three load traffic classes have been considered which are voice, multimedia and video. This work shows that MC-CAC has many advantages over SC-CAC.
