Abstract :
In this paper, we first analyze the saturation throughput and mean access delay performance of differentiated service provided by enhanced distributed coordination function (EDCF). Specifically, we investigate the impact of transmission opportunity (TXOP) and wireless channel errors on the performance of the EDCF. Based on the results from this analysis, we propose a new call admission control (CAC) algorithm that provides the desired throughput and access delay guarantees. Simulated performance results demonstrate the effectiveness of the proposed CAC algorithm
