A Dual Dynamic Call Admission Control Algorithm Based on Call Buffer in Wireless Networks
Yumin Feng · Journal of Beijing Jiaotong University · 2008
In this paper,we proposed a new call admission control scheme called Dual Dynamic Threshold access scheme with Queuing for VBR(DDT-Q).By dynamically adjusting the value of both thresholds,the system resource utilization can be improved with a better overall system award.The algorithm gives attention to the VBR character of data traffic and can adapt its service bandwidth through different thresholds and the call buffer size.Both analysis and simulation results indicate that our scheme is capable of satisfying the given Quality of Service(QoS) requirements for realtime and none realtime traffic while achieving the maximum utility.
