摘要
The present invention proposed a weighted Centroid Localisation (WCL) algorithm, which does the location estimation based only on the known positions of the gateways and the measurements of the Received Signal Strength Indication (RSSI) at the gateways. The algorithm computes the weight of the gateway based on their rank when the gateways are sorted by their relative RSSI. Simulations have demonstrated the algorithm's robustness under different multipath/fading channel conditions and its good location performance.
