A COMPUTER-IMPLEMENTED METHOD FOR ESTIMATING MOVEMENTS OF A CROWD BETWEEN AREAS

A COMPUTER-IMPLEMENTED METHOD FOR ESTIMATING MOVEMENTS OF A CROWD BETWEEN AREAS

According to an embodiment, a computer-implemented method is disclosed for estimating movements (140) of a crowd (110-111) between a first (100) and second (101) subregion in an area (130) monitored by a wireless sensor network, the wireless sensor network comprising nodes (102-105) configured to ex...

Zusammenfassung:According to an embodiment, a computer-implemented method is disclosed for estimating movements (140) of a crowd (110-111) between a first (100) and second (101) subregion in an area (130) monitored by a wireless sensor network, the wireless sensor network comprising nodes (102-105) configured to exchange a radio frequency signal through a first (132-133) respective second (130-131) link, wherein the first (132-133) respective second (130-131) link crosses the first (100) respective second (101) subregion, the method comprising the steps of exchanging radio frequency signals over the first (132-133) and second (130-131) link; and measuring respective first and second attenuations of the exchanged radio frequency signals over the first (132-133) respective second (130-131) link; and estimating based on a change in the attenuations a flow (120) of the crowd (110-112) between the first and second subregion.
