船载监控网络节点信息感知信任度模型

Node Sensing Confidence Model in Ship Borne Sensor Network

准确感知信息是船载传感网络的重要难题,船舶复杂的舱室结构和金属材质在一定程度上会影响无线传感节点感知信息的准确性。对此,在分析船舶环境及无线信号传输特性的基础上,针对船载传感网络的拓扑特性,利用无线传感网络的时空相关特性,建立节点信息感知信任度评价模型。通过仿真试验分析,验证这种利用网络拓扑特性对节点信息进行感知的信任度评价模型是有效的。

The accurate sensing information,an important target of making a precise sensor network on board ship,is challenging because the complicated structure and the metal material of the ship can cause node information inaccuracy. The topological characteristics of the ship monitoring network and the wireless signal transmission characteristics in ship environment are analyzed. A confidence model based on spatiotemporal correlation of the node information is proposed,and the simulation results show that the proposed model is effective.
