摘要

本文首先描述了IEEE 802.11 MAC层的访问控制机制，即DCF的访问控制机制，分析了DCF的基本回退算法BEB。其次，我们研究了各种改进的BEB算法，然后提出了ZDCF退退算法，这是一种基于指数的半退退算法。ZDCF灵活、易于实现，在节点规模较小时具有BEB算法的优良性能，同时避免了BEB算法在节点规模较大时的缺点。

ZDCF: An Improved DCF Solution of IEEE 802.11

This paper first described the IEEE 802.11 MAC layer access control mechanism, that is, the DCF access control mechanism, analysis the basic DCF back-off algorithm BEB. Next, we study a variety of improved BEB algorithms, and then we proposed ZDCF back-off algorithm which is an exponential-based half back-off algorithm. ZDCF is flexible, easy to implement and has excellent performance as BEB algorithms when there is small scale of nodes, while at same time avoiding the shortcomings of BEB algorithm when there is large scale of nodes.
