摘　　要：文章首先介绍了IEEE 802.16的mesh结构以及Mesh模式下协同分布式调度,对mesh结构下的三次握手机制进行了阐述,提出了原协议中三次握手机制的冲突问题,并在此基础上进行分析,针对所存在的冲突,提出了一种三次握手机制改进方法。通过分析和NS-2仿真表明,该方法性能较好,不但缩短了端到端时延,而且同时增加了吞吐量。scheduling under This paper first mesh mode, tells describes the mesh structure of IEEE802.16 and the cooperative distributed of the three-way handshaking mechanism under the mesh structure, then questions the conflict problem existing in the previous protocols, and proposes a method for improving the three-way handshaking mechanism. The network simulation results indicate that the proposed method performs well, not only shortens the end to end delay, but also raises the throughput.
