Abstract
One of the key issues in the next generation wireless cellular networks is to support multiple services, in which call admission control policy has to guarantee the different Quality of Service (QoS) requirement from diverse applications, and at the same time ensure the scarce bandwidth be utilized efficiently. In this paper, we propose a new call admission control scheme called Dual Dynamic Threshold access scheme with Queuing for VBR (DDTQ-VBR). The main novelty is that it builds upon a complete sharing approach, in which the channels in each cell are shared among the different traffic types and dual dynamic thresholds with queuing are used to meet the specific QoS requirements. Both analysis and simulation results indicate that, by using the dual dynamic thresholds in the DDTQ-VBR, we demonstrate that it is capable of satisfying the given QoS requirements for voice and data traffic while achieving the maximum utility.
