Measurement-based call admission control for adaptive multimedia in wireless/mobile networks

View publication

Abstract

Recently there is a growing interest in adaptive multimedia networking where the bandwidth of an ongoing multimedia call is variable. In this paper, we propose a measurement-based call admission control (CAC) which guarantees the upper bound of the call degradation probability defined herein. Our CAC measures the state of the cellular system in a distributed manner and reflects the observed history of the system on making call admission decisions. Also, a bandwidth adaptation algorithm to minimize the call degradation probability is presented. Simulations reveal that our CAC algorithm outperforms the upper limit CAC algorithm while maintaining quality of service.
