中文摘要：

为了节省传感器网络WSN（wireless sensor networks）中节点之间的通信能耗和提高数据传输的可靠性,提出一种考虑空间相关性的簇内多树路由协议SCMTBRP.SCMTBRP考虑了路由建立时下一跳节点的能量、节点之间的能耗距离以及空间相关性等综合传输成本,在簇内节点和簇头之间建立以簇头为根的多路由树,节点采样的数据可从多路由树中选择一条最佳路由进行传输.仿真实验表明：SCMTBRP在保证数据可靠传输的同时,能够有效节省网络中的能量和延长网络寿命.

英文摘要：

To save energy of communication among nodes and enhance the reliability of data transmission in wireless sensor networks（simply WSN）,SCMTBRP with a spatial correlation and multi-tree based routing protocol for WSN was suggested.By computing synthetical transmitting cost including energy of next-hop node,distance between nodes,and spatial correlation between nodes,SCMTBRP built multi-tree routing among nodes and a cluster head（simply CH）.Simulation results showed that SCMTBRP could save energy and prolong network lifetime when transmitting data reliably.
