We investigate the problem of efficient resource control for elastic traffic over the EDCA (Enhanced Distributed Channel Access) and HCCA (Hybrid Coordination Function - HCF - Controlled Channel Access) mechanisms of IEEE 802.11e. Our approach consi
This paper presents a novel scheduling algorithm for HCCA (Hybrid Coordination Controlled Channel Access) access model of IEEE 802.11e.The aim of this algorithm is to enhance the QoS for the support the multimedia traffic. Compared with the schedule
IEEE802.11e中QoS MAC 协议传送方式采用了混合协调功能（HCF）。其中混合式协调控制信道访问（HCCA）是基于集中轮询方式接入的，它提供了参数化的QoS接入。本文着重讨论变比特率数据流的接入控制，并提出了一种新的根据网络的实际流量，动态调整服务间隔和传输机会，来灵活的分配网络资源的算法。仿真结果表明，该算法能有效的提高网络的吞吐量和降低丢包率，大大提高系统性能。
