Abstract :
An analytical framework which employs a delay-dependent queue discipline with two and three classes of priority for handoff calls is considered. The results show that, as the number of priority classes increases from two to three classes of voice traffic, the performance of dynamic priority queuing improves by 22%. In the case of mixed voice, data, and video traffic, the performance is worse than the case when only one type of traffic (e.g., voice) with different classes is considered
