摘　　要：随着无线局域网的快速发展,人们对服务质量提出了迫切的要求,IEEE 802．11e协议应运而生,为QoS的实施提供了参考标准。EDCA是802．11e中实现QoS的分布式机制,本文基于EDCA,提出了一整套接纳控制方案和EDCA参数调节机制。本方案QoS参数考虑全面,实现简单,而且能够运用在全分布的ad hoc网络中。IEEE 802.11 based WLANs becomes more and more popular,and people begin to expect QoS support for multimedia applications.Recently,IEEE Std.802.11eTM was therefore published on Nov.2005,which gives reference to implement QoS Guarantee.EDCA is the distributed access method proposed by IEEE 802.11e,providingpreferential QoS support.The paper provides an admission control solution and parameter adjusting scheme based on EDCA.Our solution is considerate and simple to implement,and it can also be used in ad hoc network.
