Claim 0:
1. A computer-implemented method for estimating movements of a crowd between a first and second subregion in an area monitored by a wireless sensor network, the wireless sensor network comprising nodes configured to exchange a radio frequency signal through a first respective second link,
wherein the first respective second link crosses the first respective second subregion, the method comprising the steps of:
exchanging radio frequency signals over the first and second link; and
measuring respective first and second attenuations of the exchanged radio frequency signals over the first respective second link; and
estimating based on a change in the attenuations a flow of the crowd between the first and second subregion; and
wherein the estimating further comprises:
estimating based on the first and second attenuations a density of the crowd in the first respective second subregion; and
estimating based thereon a flux of the crowd between the first and second subregion.
