Embodiment Construction
[0074] The method for locating a false AP based on sensor data and signal difference fusion of the present invention comprises the following steps:
[0075] Step 1: There are real AP, fake AP and receiving end in the positioning environment. TP-LINK router 1 is the real AP, TP-LINK router 2 is the fake AP, and the mobile phone is the receiving end; the real AP is the transmitting end, and the transmitting end transmits wifi Signal, the mobile phone is used as the receiving end, the mobile phone is connected to the real AP, and receives the wifi signal transmitted by the transmitting end; take the location of the real AP as the coordinate origin, and take the initial walking direction of the person as the positive direction of the X-axis to establish a positioning coordinate system D 1 .
[0076] Step 2, the person walks in the indoor environment with the mobile phone, the starting point is the origin of the coordinates, and the distance between the starting point and the diffe...
