摘　　要：文章以无线传感器网络在建筑环境下的应用为研究背景,根据建筑能耗监测系统中无线数据传输网络特性,按位置信息对网络节点进行分簇,设计网络2级结构模型;并设计适合该网络模型的基于位置信息的WSN数据汇聚路由算法,保证簇头节点从邻居列表中选择最佳下一跳节点,最终实现与Sink节点的数据通信功能。仿真分析表明所设计的路由算法具有低时延、高可靠性、节能等优点。Under the applications background of wireless sensor network（WSN） in the construction environment,and according to the characteristics of wireless data transmission network in building energy consumption monitoring system,the nodes in the designed network are clustered based on location information,and a two-tier architecture model of this network is established.Then the location information based data aggregation routing algorithm in WSN which is appropriate for this model is designed.It ensures that the cluster head node can select the best next hop cluster head node from the neighbor list,and achieve data communication with the Sink node.The simulation results show that the designed routing algorithm has advantages of low delay,high reliability and energy saving.
