Abstract :
In this paper, a fuzzy logic call admission control (CAC) mechanism is proposed for an integrated UMTS-WLAN network. This paper grounds a novel dynamic CAC algorithm on a class-based CAC method. It uses fuzzy logic theory to generate the optimal quantity of the channel thresholds so as to assign radio resource efficiently and guarantee the Quality-of-Service (QoS) requirement. The new fuzzy logic algorithm exhibits its superiority by comparing the handover dropping probability with that of threshold-based approach. The simulation results verify that the evolved threshold-based CAC with fuzzy logic provides a lower handover dropping probability.
