Abstract

Animal tracking is important to farmers. It is mainly performed using GPS receivers. Equipping only some of the animals with GPS receivers and have the others use them as beacons for RSSI-based trilateration could be beneficial. This article tests whether such a solution is possible from an uncertainty point of view. First a range of RSSI measurements were performed. These measurements were used to create a formula for RSSI as a function of distance. The RSSI standard deviation measured in the tests gave an indication of the error, or uncertainty, related to using RSSI to calculate distance. The distance function and standard deviation were then used as a basis for simulations that calculated the uncertainty of RSSI-based range estimation. The simulations showed that the localization error related to distance estimation by RSSI was too high for it to be an efficient solution, even with a device twice as accurate as the test device.
