基于模糊数据融合的水下传感器网络节点部署策略

摘要

For nodes deployment of underwater sensor networks, based on the probability sensing model of passive sonar, a fuzzy sensing model and a fuzzy data fusion model are established with the consideration of underwater environment. The application of fuzzy data fusion algorithm for the nodes deployment of underwater sensor networks is studied, and nodes-deployment strategy based on fuzzy data fusion for underwater sensor networks ( NAFC ) is proposed. Thus, the energy consumption and the number of deployment nodes are reduced. Experimental results show that NAFC can improve the detection performance of the sensor network.%针对水下传感器网络节点的部署,根据被动声呐的概率感知模型,结合水下环境影响因素,建立模糊感知模型和模糊数据融合模型.研究模糊数据融合算法在水下传感器网络部署中的应用,提出基于模糊数据融合的水下传感器网络节点部署策略.实验证明,文中策略能有效减少部署节点,提高网络覆盖度和单个节点的检测效率,从而提高网络的检测性能.
