中文摘要： 本课题针对无线传感器网络处理能力低、存储能力和能量供应有限等局限，拟研究传感器网络的低功耗、低存储要求的路由机制，主要目标是研究基于传感器节点位置信息的路由策略，使得传感器节点不许存储庞大的路由表即可进行信息的路由和传输。课题研究的主要进展包括：1）在节点定位方面，提出了针对三维空间传感器网络的自身定位方法，通过自身定位，节点在无需专门的定位设备的情况下，就可以获取自身的（模糊）位置信息。2）在功耗控制方面，重点研究了无线传感器网络的覆盖和连通控制，以及面向移动节点定位的动态功耗控制策略。3）在路由和信息传输方面，给出了利用移动位置代理的、基于节点模糊位置信息的路由策略，同时，对分簇路由以及基于树形结构的路由开展深入研究，提出了相应的算法；此外，对于传输控制机制也开展研究，保证传输的可靠性和高效性。4）研究了传感器网络的机会通信模式，提出了面向机会传感器网络的通信信号发现概率模型和机会路由算法。5）在实验平台方面，我们利用实际的传感器节点，构建了实验平台，并针对典型的应用，构建了原型系统。

英文摘要： Because of the sensor nodes' limit capability in processing, storage and power supply, this project aims to propose routing strategies with low power consumption and low requirement of storage which are respected to benefit wireless sensor networks(WSNs) much. By designing routing strategies based on fuzzy location information of sensor nodes, no routing table is required. Process has been made mainly in the follwoing five aspects. The first is self localization with which each node can get its location information without localization equipments. We have proposed two algorithms for self localization of sensor nodes. The second is power consumption control, including coverage control and connectivity control, and the power consumption control in localization applications with mobility sensor nodes. The third is routing and transmission control, including mobility agent based location service for geographic routing, cluster routing, tree structure based routing in WSNs, and the congestion control. The fouth is about opportunistic network framework, including the detection probability estimation model and routing strategies in opportunistic WSNs. The last one is that we have built up test platform and application prototype for typical WSN applications.
