Practical Fingerprinting Localization for Indoor Positioning System by Using Beacons

Figure 15

Average location error at different measurement places at the edge of the testbed corridor: (a) measurement place A, (b) measurement place B, and (c) measurement place C. PF: proposed practical fingerprinting; Wk-NN: weighted k-nearest neighbor; WCL: weighted centroid localization; RF: reference points.
