An Indoor Emergency Guidance Algorithm Based on Wireless Sensor Networks

Traditional safety in the important building is noisy, expensive and has big drawbacks in guiding trapped people to the safety exit gate. Hence, a new mechanism is needed to rescue human from the fire building and to guide them to the best safety gate. Wireless Sensor Network (WSN) combined with a proposed guidance algorithm is an important indoor application. This paper proposes an indoor emergence guidance algorithm based on WSN to guide people to a building exit gate while helping them avoid a hazardous area. WSN is responsible for real-time monitoring of the environment, and when emergency event is detected the proposed algorithm will be invoked and a real-time guidance will assist to rescue the trapped people very fast. The proposed guiding mechanism has been successfully studied and verified through real test bed implementation using Telosb motes.
