motion sensing method based on parametric perturbation pattern of wireless LAN which is stabilized by dummy traffic

摘要

The present invention detects movement (motion) within the wireless LAN coverage based on the wobble pattern when the wireless LAN parameter is suddenly fluctuated in a specific pattern in a state where the wireless LAN parameter is stabilized by the dummy traffic Technology. At this time, in the method of transmitting dummy traffic, it is preferable that the wireless LAN access point continuously transmits dummy data to the wireless LAN station in the form of a UDP packet. More particularly, the present invention relates to a wireless LAN communication system in which a plurality of wireless LAN communication devices spaced apart from each other in a specific space such as a home or office are constantly exchanging wireless LAN dummy traffic, The present invention relates to a motion detection technique based on a wobble pattern of a wireless LAN parameter that can determine that there is something in a space when a wobble occurs and a variation pattern of the wobble indicates a specific pattern.
