Fire evacuation simulation for the case of a non-symmetrical metro station using Wireless Sensor Network

This paper describes a solution for emergency evacuation of a non-symmetric metro station in the case of fire using Wireless Sensor Network (WSN). Comparative simulation research of monitoring and evacuation of a metro station fire both with and without WSN was carried out. A simulation model was constructed using WSN positioning technology. It was found that WSN positioning technology helped solve blind area rescue and evacuation in the metro fire disaster, especially for evacuation in a non-symmetrical environment. The simulation results showed that by using WSN, evacuation time was greatly shortened so that the scope of the possible disaster could be reduced; this offers some referential significance for realistic evacuation.
