| 摘 要： | 从理论上分析了IEEE802.11e协议中EnhancedDistributedCoordinationFunction(EDCF)的性能。目前,EDCF作为实际实现中的标准接入机制而成为研究的热点,已有大量文献分析了EDCF中参数的选择及其对网络性能的影响。但是在以前的工作中对使用TransmissionOpportunity(TXOP)时以及非理想信道条件下EDCF系统的性能分析却很少。文章的主要工作就是从理论上分析了采用TXOP以及考虑信道误码时EDCF的性能。

| Abstract: | This paper focus on the analytical approach to evaluate the performance of the Enhanced Distributed Coordination Function(EDCF).The EDCF is now attracting many researchers' attention due to its practical worth as a standard mechanism,and it presents a comparative study of the different EDCF parameters selection and their impact on network utilization and performance.The use of transmission opportunity(TXOP)and the effect of non-ideal channel condition received little attention in previous analytical studies.Specifically,we concentrate on discovering the characteristics of the TXOP and the channel detection error in the way that they influence the performance of the EDCF. |
