中文摘要： 水下传感器网络主要采用声波作为通信手段，而水声通信具有延迟大、传播损失大、多途效应和多普勒频移效应明显的特点。因此，水下传感器网络的研究问题极少能直接采用陆上无线传感器网络的研究成果。课题针对水下传感器网络的定位、媒体接入、路由和实验系统展开研究工作，主要成果包括：（1）综述现有水下传感器网络研究现状；（2）针对定位和跟踪问题提出了稀疏锚结点条件下的移动轨迹追踪算法及海上移动船只入侵监测算法；（3）针对媒体接入和同步问题，提出了吞吐量高效的时分复用媒体接入算法和负载自适应的时分复用及竞争协议混合接入算法，以及能量高效的同步算法；（4）针对数据传输问题，提出了能量平衡的路由算法和面向事件的数据融合传输算法；（5）提出了水下监测网络的体系结构，并完成了原型系统的开发工作。在上述研究基础上，课题组在包括ICDCS、IEEE Transactions on Vehicle Technology、IEEE Transactions on Instruments and Measurement等学术期刊和会议共发表论文23篇，其中SCI 检索3篇次，EI检索19篇次，申请国内专利7项，授权2项。

英文摘要： Acoustic communication is the major media for underwater sensor network. There are a lot of specialties in acoustic communication, such as long latency, large transmission attenuation with multipath effect and Doppler frequency shift effect. Therefore, the research results on wireless sensor network with microwave communication cannot be directly exploited in underwater acoustic sensor networks. This project focuses on the research problems of underwater acoustic sensor network, including node localization, MAC protocol, routing scheme and prototype development. The major research results cover：(1) review on recent progress on research results of underwater acoustic sensor network; (2) proposing the node tracking algorithm for sensor network with low density of seeds and the intrusion detection problem for ships in the sea; (3) proposing throughput efficient MAC protocol , throughput adaptive MAC protocol and energy efficient synchronization algorithm; (4) proposing the energy balancing routing algorithm and event oriented data integration and transmission algorithm; (5) proposing the architecture for environmental information surveillance systems and developing the prototype of underwater acoustic sensor networks. Based on the research, 23 papers are published on important academic journals and conferences, including ICDCS, IEEE Transactions on Vehicle Technology、IEEE Transactions on Instruments and Measurement, among which 3 are indexed by SCI and 19 are indexed by EI. Meanwhile, 7 domestic patents have been applied, 2 of them have been authorized.
