中文摘要：
针对海洋传感器网络中节点会随着海流运动漂流而离开初始位置产生节点迁移的问题研究了网络部署方法和拓扑形成策略。建立了海洋传感器网络模型和海流运动模型，分析了在典型海流运动中海洋传感器节点的迁移规律，并给出了海洋传感器网络的部署方法。此外，针对海洋环境中通信时延高、能耗大的特点还归纳了海洋传感器网络拓扑控制的目标需求，设计了一种适合该场景的拓扑控制算法，该算法采用合适大小的簇来形成三维拓扑结构。仿真实验表明该算法能计算出海洋传感器网络的方位偏移量，且能获取较优的拓扑结构，降低网络通信时延，还通过有效节能延长了海洋传感器网络的生命期。
英文摘要：
Considering that it is possible for sensor nodes in ocean sensor networks to drift with the ocean current movement, so the nodes may move away from their initial locations, the paper studies the networks deployment methods and topology formation strategies. An ocean sensor network model and a current movement model are established firstly, and then the nodes migration laws in typical ocean currents are analyzed, and a deployment method for ocean sensor networks is proposed. Moreover, the topology control objectives in ocean environment where communication yields large delay and high energy consumption are concluded, and a topology control algorithm for ocean environment is designed. The algorithm can format a three-dimensional topology by clusters with proper size. The simulation experiments suggest the algorithm can calculate the position offset of ocean sensors, and it can acquire an optimal topology which reducing the network communication delay and prolonging the ocean sensor network life- time.
