| 摘 要： | 定向扩散协议是一种用于无线传感器网络的数据分发协议.在定向扩散中,兴趣和探测数据采用泛洪的方法在网络中散布,这将引起广播风暴导致网络能量的大量消耗.在网络中通过形成簇结构可以缓解广播风暴问题,每个节点利用本身的地理位置信息自组织形成虚拟地理网格簇,簇中仅有一个节点负责兴趣和探测数据的广播.模拟试验表明,这种方法有效地降低了网络的能量消耗.

| Abstract: | Directed diffusion is a data dissemination protocol for wireless sensor networks.In directed diffusion,flooding is used for dissemination of interest and exploratory data,which will bring broadcast storm resulting in substantial energy consumption of networks.Forming cluster can alleviate broadcast storm problem.Virtualgeographic grid clusters are constructed self-organized by nodesusing geo-graphic location information.In a cluster,only one node is responsible for broadcasting interest and exploratory data.The simulation shows that the method effectively reduces the network energy consumption. |

| Keywords: | wireless sensor networks data-centric routing directed diffusion broadcast storm clustering protocol |
