A Fuzzy-Based CAC Scheme for Cellular Networks Considering Security

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. In this paper, we propose a new CAC scheme which considers for acceptance decision except other parameters also the security. We call the proposed system FACS-S (Fuzzy Admission Control - with Security). We evaluated by simulations the performance of proposed system and show that the FACS-S has a good behavior.
