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