Admission Control for Multi-Traffic in Wireless Multi-Channel Communication Network Based on Discrete Time Queue

In this paper, an admission control scheme with priority for real-time traffic is designed, and a discrete time Geo

/s (preemptive priority) queue model is proposed to study the performance of the multi-traffic admission control scheme, which based on the running mechanism of the wireless multi-channel communication network and the various quality of service (QoS) requirement of multitraffic. Using matrix-geometric solution method, we get the performance measure, such as, average queue length for both traffic, blocking probability of real-time traffic and utilization rate of channel. And computer simulations verify the accuracy of the model
