论文摘要(本文首先介绍了802.16 Mesh模式下的MAC帧结构，然后对协议中的协同分布式调度机制进行了详细的阐述。根据协议的规定，在NS中编写了新的MAC层源代码，对802.16的MAC调度进行了仿真，实现了Mesh模式下协同分布式MAC调度过程，并对三次握手过程、数据子帧minislots分配成功率和minislots利用率进行了分析) 有利于我们学习-Abstracts (This article first introduced the 802.16 Mesh mode MAC fr a me structure, and then the agreement of the collaborative distributed scheduling mechanism in detail. According to the agreement stipulated in the NS in the preparation of a new MAC layer source code for 802.16 the MAC scheduling simulation to realize synergies Distributed Mesh mode MAC for the activation process, and three-way handshake process, the data sub-fr a me and the success rate of minislots allocated minislots utilization analysis) will help us learn
