ABSTRACT:
An indoor location awareness method for locating a device using device-observable signals of known proximity sensors and device-unobservable signals of known proximity sensors. The exclusion of the possibility that the device is within an unobservable proximity sensor's range increases the knowledge of the device's true location. In addition to defining the location of the device, the device can predict the arrival and departure of unobservable proximity sensors as it moves throughout the environment.
