- Abstract
With the increase of outdoor activities,the anti-lost demand grows rapidly. A method based on low power bluetooth(BLE) received signal strength indicator(RSSI) becomes a compelling alternative. It has the advantages of low power consumption,low cost,etc. However,the bluetooth RSSI signal is easily disturbed,making it difficult for practical application. In the view of this,an anti-lost algorithm is proposed based on RSSI hypothesis test. Firstly,a large number of RSSI sampling sequences are captured and analyzed. It爷s found that almost all of the RSSI samples are consistent with the normal distribution. Then a hypothesis test is designed for the RSSI sequence dynamically. Next,a corresponding state machine is designed to dynamically determine the relative position of the host and slave. Finally,according to the previous information,whether the position is safe can be judged. The experiments and evaluation results show that the algorithm can achieve a good anti - lost performance.
