中文摘要：
为了优化Zig Bee网络媒体接入控制（Media access control,MAC）协议性能,提出一种基于饱和负载的MAC层信道访问机制。通过马尔科夫链对网络节点状态转化过程建模,对基于信道访问机制的网络吞吐量和节点能耗进行了数学分析。研究了网络参数NB、amin BE对节点信道冲突概率、网络吞吐量和能耗等性能的影响。分析结果表明：该模型准确地描述了基于饱和负载的Zig Bee网络信道访问机制,对协议参数进行合理的设置能够改进MAC协议吞吐量和能耗性能。
英文摘要：
To optimize the performance of media access control（MAC） protocol for Zig Bee network,a mechanism based on saturated traffic for channel competitive access is proposed. This paper establishes a Markov chain model for the process of node state transition. The numerical analysis of throughput and node average power consumption based on the mechanism is carried out. The impact of protocol parameters such as NB and amin BE on the performance of conflict probability,throughput and node average power consumption is researched. The results show that this model can describe the mechanism of channel competitive access well and that the reasonable settings for parameters can improve the performance of the MAC protocol.
