| 摘 要： | 为延长网络生存时间，提出一种基于事件驱动的传感器网络数据收集协议。该协议根据自适应评估模型选出簇头，当有兴趣事件发生时，簇内成员节点将收集到的数据传递给簇头，簇头进行数据融合并向sink发送数据收集请求。sink接收到数据请求包后，移动到这个簇头附近开始收集簇内兴趣事件。仿真实验结果证明，该协议能有效降低节点能耗，延长网络寿命。

| Abstract: | An event-driven data gathering protocol in mobile wireless sensor networks is proposed.The protocol uses the adaptive cluster head evaluating model to elect cluster head.Upon interesting events take place,the member nodes gather them and send to the cluster head.After fusing these data,the cluster head transmits a data collection request packet to the sink.When receiving this packet,the sink moves to the cluster head nearby and gathers data.Both theoretical analysis and simulation studies show that this protocol can prolong to network lifetime efficiently. |
