| 摘 要： | 为了保证网络负载增加后无线局域网的QoS,在EDCA机制的基础上运用了预约竞争窗口维护技术，当网络处于低负载时，性能与原接入机制一样，随着负荷的增加，在稳定条件下可以大大减少碰撞概率，从而既保证高优先级业务的QoS，又能提高整个网络的吞吐量。

| Abstract: | To guarantee the QoS of WLAN(Wireless Local Area Network) after the network load increased,the technology of reserved contention window maintenance was applied to EDCA mechanism.When network was in low load,the performance was the same as the original access mechanism.As the load increased,it could greatly reduce the collision probability under stable condition.Therefore it can not only support QoS of the high priority traffic,but also improve the throughput of the whole network. |
