The unpredictable nature of the wireless network and exponential growth in traffics with different quality of service requirements has led hardware complexity to escalate. In order to effectively control and manage the network traffics, there is a need for intelligent Call Admission Control (CAC) in admitting traffics into the wireless network that provides necessary quality of service. In this paper, the authors propose a Fuzzy Logic partition-based Call Admission Control (FZ CAC). The scheme primarily partitions the total link bandwidth into three which corresponds to Constant Bit Rate (CBR), Variable Bit Rate (VBR) and HandOver (HO) services.
