Modern wireless cellular networks (WCNs) carry different types of services, including voice, video, data, web traffic, etc. In order to provide high-quality multimedia services to anyone, anywhere, at any time with the consideration of user mobility, network designers need to implement optimal mechanisms that can trade off between Quality of Service (QoS) and Channel Utilization (in other words, Resource Utilization). This paper presents a dynamic guard channel allocation (DGCA) scheme, which can adaptively adjust the number of reserved channels for handoff calls to achieve this goal. Heavy-tailed distributions are used to represent the multimedia traffics. SimPy is used to build the simulation model [1].
