为解决802.11e网络的公平性问题,提出一种TXOP动态分配方法,在节点传输前,根据碰撞次数估计碰撞程度,根据估计得到的网络负载情况调整节点的TXOP,使不同优先级、不同传输速率的业务获得相应的TXOP值。理论分析和仿真结果表明,该方法在采用不同发送速率的业务间,能保证吞吐量的公平性,并减少分组重传次数,降低分组传输平均时延。
In order to solve the problem of fairness of 802.11e networks, a TXOP dynamic allocation method is proposed to estimate the collision degree according to the number of collision before node transmission. The TXOP of nodes is adjusted according to the estimated network load, so that different priorities and different transmission rates The business received the corresponding TXOP value. Theoretical analysis and simulation results show that this method can ensure the fairness of throughput and reduce the number of retransmission and reduce the average delay of packet transmission among different transmission rates.
