研究传感网络通信效率优化问题。传统的传感网络通信过程中，简单的以通信节点优先级的高低进行通信调度，没有考虑调度过程中的优先级的设定过程是否达到了最优，在相似优先级的认定过程中，存在较大缺陷，通信效率不高。提出采用马尔科夫链模型的传感网络通信优化方法。计算通信过程中的链路冲突概率，建立马尔科夫链模型，在上述模型中，用低优先级业务组重传的均值代替初始值，并对所有的通信数据进行分簇处理。在通信的过程中，对信道吞吐量和信道内的丢弃概率进行计算，衡量传感网络通信性能，保证分级的准确。实验结果表明，改进通信算法对于高优先级数据优先传送的作用是非常明显的，并且数据流分组丢失的情况也得到了有效遏制，更适用于节点数比较高的网络中。

Research sensor network communication efficiency optimization problem. This paper presented a sensor network communication optimization method based on Markov chain model. Link conflict probability was calculated in the process of communication, and then Markov chain model was established. In this model, it used a low priority po-sition to the retransmission of average instead of the initial value, and treated all the communication data with data clustering. In the process of communication, the channel throughput and channel discarding probability were calculat-ed and the sensor network communication performance was measured, to guarantee the accuracy of classification. The experimental results show that the improved communication algorithm for the effect of priority transmission of high pri-ority data is very obvious and the data flow of packet loss also is effective.
