| 摘 要： | 提出了一种针对无线传感器网络的路由协议,该路由采用最小传输成本生成树的数据汇聚机制。具体方法是首先将传感区域内的传感器节点采集的数据传送给传感区域内离汇聚点最近的节点,将这些数据进行汇聚操作后,将汇聚的结果通过最短路径传递给网络汇聚点。仿真结果显示,采用最小传输代价生成树的路由协议能减少数据传输量50%-80%,并具有较小的传输时延。

| Abstract: | A routing protocol for wireless sensor networks was proposed.The protocol used a data aggregation scheme of minimum transmission cost spanning tree.In this protocol,the node in sensing region which is nearest the sink acts as the aggregation point.All other nodes in sensing region send their data to this aggregation node,then sends the aggregation information to the sink along the shortest path.Experimental results show that the data routing protocol can cause roughly 50%～80% fewer transmissions and a bit shorter transmission delay. |
