摘　　要：作者在基于能量消耗分析和蚁群算法的基础理论指导下,针对无线传感网路径选择优化问题,进行了深入的理论、方法与模型的研究工作.主要步骤为:首先根据节点剩余能量确定成员节点当选为簇首节点的概率;其次根据成员节点距离簇首节点最近的原则进行分簇;最后确定簇内汇聚节点aggregator进行数据融合处理,确定信息发送节点,通过多跳路由方式给Sink传输数据,然后借助蚁群算法进行路径优化分析研究,通过仿真实验表明,该方法较常规方法有了很大的改进和效果.In this paper,based on energy consumption and ant colony algorithm,the path choice of wireless sensor network optimization was studied,including the research work,model theory,and the method of depth.The main steps were as follows： first,according to the residual energy of the nodes,the member nodes were elected as cluster head node probability; secondly,nodes were divided acconding to their distance to the cluster head node; finally the cluster of aggregator nodes were used for data fusion processing to determine the information sent to the Sink node.At last,we transmit data via multi-hop routing method,and used ant colony algorithm to do optimization and analysis.
