Zusammenfassung:	A navigation method for indoor escaping is executed by at least one processor of an electronic device. At least three message transmitters fixed in a building around the electronic device are connected with the electronic device. Messages are received from each message transmitter. The messages include location information of each message transmitter and a floor plan of the building. A current position of the electronic device is determined according to the location information of each message transmitter and signal strength of each connection between the electronic device and each message transmitter when receiving a fire alarm and a position of the fire. An optimal escape route is calculated according to the floor plan of the building, the position of the electronic device, and the position of the fire. Navigation is provided to a user of the electronic device to escape from the building.
