Bluetooth as a victim detection sensor

This work investigates the promise of Bluetooth wireless communication protocol as a victim detection sensor. The fact that cellphones are carried by people can lead rescue robots to track Bluetooth devices alongside other victim detection sensors (e.g., Heat, CO2, Voice, Visual motion detector, etc.). Bluetooth communication protocol can provide the received signal strength (RSS) as an indication of the distance between the two devices in communication. Therefore, the RSS can be used to estimate the distance between the robot and any possible Bluetooth device carried by a victim. This can lead a rescue robot to check other victim sensory data to confirm the existence of a victim in the vicinity of the detected Bluetooth emitting device.
