Performance Analysis on Channel Assignment Scheme in Mobile Networks
This paper presents a general framework for a wide range of Call Admission Control (CAC) algorithms. For several CAC schemes, which are a subset of this general framework, an analytical performance evaluation is presented for a mobile wireless network. These CAC algorithms consider a variety of mechanisms to prioritize traffic in an attempt to support different levels of Quality of Service (QoS) for different types of calls. The authors' mechanisms include dividing the handoff traffic into more than one class and using guard channels or allowing channel splitting to admit more handoff calls. Furthermore, their analysis relaxes the typically used assumptions of equal resource usage for voice and data calls.
