摘要

Call Admission Control (CAC) is one of the resource management functions which regulates network access to ensure QoS provisioning. However, the decision for CAC is very challenging issue due to user mobility, limited radio spectrum and multimedia traffic characteristics. Several schemes have been proposed for CAC in wireless cellular networks. However, during to the complexity of CAC in wireless environment, many simplified models and assumptions are made. Some schemes consider that each mobile node will make hand-over to neighbouring cells with equal probability, which may be not accurate in general. For this reason, the intelligent and heuristic methods are needed. We proposed a fuzzy-based CAC system by considering the priority of the on-going connections. We called this system FACS-P. In FACS-P, as priority parameter, we considered only one parameter (service request). We extended our work by adding different priorities. We call this system FACS-MP. In this paper, we evaluate by simulations the performance of the proposed system. From the simulation results, we conclude that the FACS-MP makes a good differentiation of different services and has better behaviour than FACS-P.
