使用双基站无线传感器网络进行电网连续灾害追踪与预警研究

Dualsink-based Continuous Disaster Tracking and Early Warning in Power Grid by Wireless Sensor Networks

为应对山火、泥石流和洪涝灾害等连续大面积灾害性事件,针对无线传感器网络应用中资源受限以及通信量大等特点,从工程设计角度出发提出了一个基于动态、静态双基站的无线传感器网络体系结构,设计了一种用于准确跟踪连续灾害对象的DCDT算法。仿真结果表明,该网络体系结构比传统的单基站网络架构更易于延长无线传感器网络的使用寿命,对于电网灾害追踪与预警有很好的应用意义。

From the engineering point of view, we propose a novel dual sink-based continuous disaster tracking （DCDT） algorithm, which consists of a static sink and a mobile sink guided by GIS. The two sinks can cooperatively work in an intelligent model in which the mobile sink can calculate the right position to collect the information from boundary nodes; in which the static one can reduce much message transmission as well as energy consumption based on centroid algorithm. The simulation result shows that our solution can distinctly prolong the network life time than single sink network in continuous object tracking.
