| Abstract: | In this paper, in order to compensate for the defects of 802.11DCF mechanism, the size and growth rate of competition window are dynamically adjusts for the improvement of the Binary Exponential Back-off algorithm. The improved algorithm makes the nodes with more opportunities to access channel in serious channel conflict. |

| Keywords: | 802 11DCF contention window binary exponential back-off |
