摘　　要：为了更好地对IEEE802.16 Mesh协同分布式模式下的网络时延进行评估,利用已有的随机分布式模型,在介绍了IEEE802.16 Mesh的MAC帧格式的基础上,对接入延迟和3次握手的延迟进行了性能分析和仿真分析。分析结果表明,随着回退时隙数量的增加,MSH-DSCH消息的接入延迟和3次握手延迟会增加,仿真结与理论分析结果相同。In order to evaluate the packets delay in coordinated distributed scheduling in IEEE 802. 16 Mesh networks, based on the introduction of MAC in IEEE802.16 Mesh, the access delay and the three-time handshake process delay were studied using the basic randomly distributed model. The analytical result shows that access delay and three-time handshake process delay will increase with the rise of MCL, and the simulation result is accord with the theoretical analysis.
