A Distributed Emergency Navigation Algorithm for Wireless Sensor Networks
نویسندگان
چکیده
Navigation services in emergency scenes could be an important application of wireless sensor networks for saving human lives. In this paper, we propose a navigation algorithm which emphasizes on safely guiding people to quickly escape from a hazardous area. Our design allows multiple exits and multiple emergency events in the sensing field. At normal time, sensors are responsible for monitoring the environment. When emergency events are detected, our protocol can quickly identify hazardous areas and sensors can establish escape paths that are as safe as possible leading to exits. In particular, when surrounded by hazards, sensors will try to guide people as farther away from emergency locations as possible. Simulation results and our prototyping experiences are also presented. Compared to existing results, our protocol incurs lower latency and costs less message overheads.
