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

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.
