摘要

本文研究了IEEE 802.11标准MAC协议在DCF(分布式协调功能)和PCF(点协调功能)下的综合数据和语音传输性能。通过仿真，我们评估了各种协议参数下的网络性能，特别是话音流量的延迟抖动。给出了影响延迟抖动的主要因素。数值计算结果表明，为了提高IEEE 802.11的性能，必须选择合适的参数，并在话音站数量和数据流量吞吐量之间做出妥协。从理论上推导了协议的性能，并通过仿真结果进行了验证。

Performance analysis of IEEE 802.11 WLAN to support voice services

This paper studies the performance of the IEEE 802.11 standard MAC protocol for integrated data and voice transmission with the DCF (distributed coordination function) and the PCF (point coordination function). By simulation, we evaluate the network performance for various protocol parameters, especially, the delay jitter for voice traffic. The main factor to influence delay jitter is given. Numerical results show that it is important to choose appropriate parameters and compromise the number of voice stations and the data traffic throughput to get the enhanced performance of IEEE 802.11. The performance of protocol in theory is derived and is verified by the simulation results.
