这篇论文建议修正到分布式的协作功能(DCF ) 在 IEEE 802.11 无线本地区域网络(WLAN ) 改进隧道利用。在修改 DCF,当一个车站为隧道竞争了时,它可以连续地把多重数据框架传给一样的目的地,它被称为冲破的传播(TB ) 。当在 TB 连续地播送的数据包的最大的数字被设置是 2 时,表演被期望是最好。理论分析和模拟结果证明与 standardDCF 相比,修改 DCF 能增加产量并且减少 WLAN 的延期,和修正不介绍任何另外的控制开销。
This paper proposes a modification to distributed coordination function (DCF) to improve the channel utilization in IEEE 802.11 wireless local area networks ( WLANs). In the modified DCF, when a station has contended for the channel, it may transmit multiple data frames continuously to the same destination, which is called transmission burst(TB). When the maximum number of data packets transmitted continuously in a TB is set to be 2, the performance is expected to be the best. The theoretical analysis and simulation results show that compared with the standard DCF, the modified DCF can increase the throughput and decrease the delay of the WLAN, and the modification does not introduce any additional control overhead.
