In an emergency, wireless network sensors combined with a navigation algorithm could help safely guide people to a building exit while helping them avoid hazardous areas. We propose a distributed navigation algorithm for emergency situations. At normal time, sensors monitor the environment. When the sensors detect emergency events, our protocol quickly(More)
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,(More)
