Abstract :
In order to calculate the RSSI of the virtual reference tags accurately, this paper proposes a method that based on log-distance path loss model. Add some real reference tags in the original layout, read the RSSI of real reference tags twice in a short time interval to calculate the path loss exponent and the average environmental impact value nearby tags by using the model. The virtual reference tags will choose the exponent and the impact value of the nearest real tag to calculate the RSSI. Experimental result shows that compared with VIRE algorithm, the proposed method provides a higher accuracy.
