Call Admission Control (CAC) is a fundamental mechanism used for Quality of Service (QoS) provisioning in cellular mobile networks. An effective CAC scheme needs to be adaptive to the changing traffic patterns and thus dynamic approach is preferred. Unlike the conventional CAC schemes, the present paper proposes a scheme that does not use complicated analytical models. Instead it is based on the fuzzy logic control and supports heterogeneous traffic applications like voice, data, etc. In the proposed mechanism, the amount of guard channels to reserve are controlled dynamically on the basis of varying network parameters like call dropping probability, network load, etc. and also takes into account of diverse classes of traffic applications. Analysis showed that the proposed fuzzy logic-based mechanism demonstrated better performance compared to the fixed channel reservation scheme. The results also revealed that fuzzy logic-based CAC mechanism achieved higher channel utilisation while maintaining the required QoS for different classes of applications.
