Abstract

The fuzzy-based call admission control (CAC) scheme is presented in this paper to offer adaptive services for multimedia stream in next generation wireless networks. Since the contemporary wireless networks will provide a variety of services and each service has multiple levels of quality requirements, but the resource is always scarce. Thus, the adaptive resource allocation for bandwidth is an important issue. In this paper, the proposed CAC scheme considers the adaptive resource requirements to enhance the efficiency of channel utilization in wireless networks. When a new call is arriving, the CAC scheme will evaluate if the available bandwidth can satisfy the requirement of incoming call. Whenever the available bandwidth is not sufficient to meet the requirement, the CAC scheme is based on fuzzy logic to choose an existing call, of which the allocated bandwidth will be degraded in order to release some bandwidth for the incoming call. From the results of simulation, the proposed scheme is superior to the existing scheme.
