Design of an experimental indoor position system based on RSSI

At present, although the position theory and algorithm of WSN(Wireless Sensor Network) have been widely researched, however, the real application of WSN position technology is just on the initial stage, in response to which, this paper designs an indoor experimental position system based on RSSI, which selects trilateral ranging method as position method and utilizes CC2510 chip as wireless node. Meanwhile, this paper designs an experimental model for implementation. In the end, this paper analyzes the experiment data and proposes several suggestions for future work, such as improving position algorithm, which is quite meaningful for further research. Moreover, the result of the experiment shows that the absolute error is around 2 meters, which demonstrates that this system has a high degree of accuracy.
