| Summary: | 碩士 === 國立交通大學 === 資訊學院資訊科技產業專班 === 96 === Wireless sensor networks provide a convenient way to monitor the physical environment. However, it is not always possible to have a deployment of a sensor network in the region of interest. In this case, how to obtain the environmental situations is a big challenge. In this paper, we propose to use mobile sensors to quickly capture and analyze the events occurred in a region without any deployment of sensor networks. The idea is to request mobile sensors to fully scan the environment to find out where events occur and then dispatch mobile sensors to event locations to conduct more advanced data collections. We propose a priority-based dispatch scheme for mobile sensors to visit events according to events' locations and priorities. In particular, events with higher priorities and shorter moving distances will be visited first. In this way, mobile sensors can quickly finish their jobs and the most important events can be analyzed earlier before they disappear. We have implemented a prototyping system to demonstrate our dispatch idea. Simulation results are also presented to verify the effectiveness of the proposed schemes.
