A SECURE-AWARE CALL ADMISSION CONTROL SCHEME FOR WIRELESS CELLULAR NETWORKS USING FUZZY LOGIC AND ITS PERFORMANCE EVALUATION

摘要

As the demand for multimedia services over the air has been steadily increasing over the last few years, wireless multimedia networks have been a very active research area. To support various integrated services with a certain Quality of Service (QoS) requirement Call Admission Control (CAC) is a good strategy. The 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. In this paper, we propose a secure-aware CAC scheme for wireless cellular networks using fuzzy logic. For evaluation of proposed scheme, we implement a new simulator called Fuzzy CAC Simulator (FCACS). We evaluated by simulations the performance of proposed CAC scheme and show that the proposed scheme has a good behavior.
