摘要: IEEE 802.11協(xié)議的MAC層通過二進制指數(shù)退避算法實現(xiàn)對媒體的爭用，該文提出一種增強的退避算法，對網(wǎng)絡中的動態(tài)站點數(shù)進行估計，自適應改變退避算法的競爭窗口，以提高網(wǎng)絡的性能。Abstract: The MAC layer of the IEEE 802.11 standard adopts an exponential backoff scheme to access media. This paper provides an enhanced backoff scheme, which changes Contending Windows(CW) adaptively by estimating the number of active stations in network to improve the efficiency of network.
