Evaluation of a Fuzzy-Based CAC Scheme for Different Priorities in Wireless Cellular Networks

Abstract

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. We proposed a fuzzy-based CAC system by considering the priority of the on-going connections. We called this system FACS-P. In FACSP, as priority parameter, we considered only one parameter (service request). In our previous work, we extend 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 simulations results, we conclude that the FACS-MP make a good differentiation of different services and has better behaviour than FACS-P.
