A new call admission control scheme for real-time traffic in wireless networks

Abstract

In this paper, we introduce a framework to explain an adaptive call admission control for real time traffic of a wireless network in order to improve the system performance in terms of call blocking probabilities. The key contribution of the work explained in this paper constitutes the application of a transcoding scheme of the real-time voice for a call admission controller. The advantage of employing the adaptive call admission control is illustrated by the performance curve showing the reduction in the overall call blocking probability of the system. The proposed scheme attempts to supplement existing call admission control schemes, rather to replace them.
