中文摘要：

随着无线传感网络工作环境的日趋复杂，离群节点的数量成随机分布，目标定位很难控制。传统的无线传感网络中的节点选择算法都以能量和路径最优化关系为基础，通信过程中没有考虑节点中的离群特征点问题，通信协议仅仅依靠节点属性的关联性选择节点，一旦网络中产生大量的离群特征点，则离群节点数据属性偏离原始特征，将造成空间失连，导致协议通信效率变差。提出了一种改进的无线传感网络通信优化算法。通过对节点的剩余能量进行对比，选取合理的节点作为簇头节点，并对簇头节点进行均匀分布。将多跳传输方法和单跳传输方法结合，避免传统协议过于单一的缺陷，从而实现通信的优化。实验结果表明，利用改进后的算法进行路由协议构建，能够平衡每个簇头节点之间的能量消耗，从而有效延长网络生存时间，提高无线传感网络的通信效率。

英文摘要：

The work environment of wireless sensor network （WSN） is becoming more and more complicated. The number of outlier nodes distribute randomly. The target localization is difficult to control. An improved communication optimization algorithm of WSN was proposed. By comparing the residual energy of node, the reasonable nodes were selected as the cluster head nodes. The cluster head nodes were arranged in uniform distribution. The multi hop transmission method and single hop transmission method were combined. The defect that the traditional protocol was too single was avoided, and the optimization of communication was realized. The routing protocol was constructed with the improved algorithm. Simulation result shows that the improved algorithm can balance energy consumption between each cluster head node, and the network survival time can be prolonged effectively. The communication efficiency of WSN is improved.
