中文摘要: 水面无线传感器网络具有规模大、拓扑结构易改变等特点,现有的各类路由方法无法有效应用于这类实际应用。本项目对水面无线传感器网络中存在的时空相关性关系进行了实验研究和理论分析,提出了利用采用主题模型理论将相关性数据进行聚类的方法,减少不必要的通讯消耗。本项目将路由优化问题进一步转化为一个组合优化问题并分析其主要特点,提出使用蚁群算法求出合理的拓扑规划,提出了基于蚁群算法的路由机制并开发了相应软件。水面无线传感器网络具有节点可利用水流等外力进行移动的能力,本项目据此提出了在网络中增加母节点的策略,通过母节点来定向补充失效节点,极大的延长了网络的有效工作时间。在对水面无线传感器网络的应用特性进行全面分析的基础上,我们研究以图形化的方式动态仿真和分析网络的工作情况,开发完成了两款仿真模拟软件并申请了相关专利。

英文摘要: Water wireless sensor networks are characterized by large-scale and changeable topology. Hence, available routing schemes can't work well within water wireless sensor networks regime. We study the spatial-temporal correlations existing generally in water wireless sensor networks with experimental study and theoretical analysis. Topic model theory is adopted to cluster the correlated data to reduce unnecessary communication expense. The routing optimization problem is converted into a combinational optimization problem, which is resolved by ant colony system to achieve the ideal topology scheme. We both accomplish the algorithms and the corresponding software copyright. Nodes in water wireless sensor networks can move with tiny energy consumption, based on which a mother node notion is put forward . The simulation results show that this mechanism can significantly prolong the lifetime of water wireless sensor networks. In addition, we develop simulation auxiliary software to enhance simulation and analysis performance based on the existing simulation platform.
