| description | The invention discloses a safe compression perception positioning algorithm based on a square median under the attack of malicious nodes. The algorithm comprises steps of firstly, randomly dividing all measurement values based on receiving signal intensity into multiple measurement value subsets; then, using the compression perception reconstruction technology to estimate target positions corresponding to the subsets; calculating respective residual error medians of the subsets, finding a residual error vector with the smallest median, and using the residual error vector to define a verification parameters; in order to complement information loss caused by few measurement value samples, correcting an initial verification parameter which is used for finding an attacked malicious node; and finally, according to the verified unattacked measurement value sets, using the compression perception reconstruction technology to find the final target position and carry out estimation.
