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)
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)
