A Novel Ranging Method Based on RSSI
The ranging technique based on RSSI is often used in localization of wireless sensor network (WSN).Due to external interferences, the RSST fluctuates a lot and then a novel ranging method is presented.It establishes a database of mapping relationship between the RSSI and the distance range, then the distance between the transmitter and the receiver can be drawn by summing weighted of the distance spaces obtained through querying the mapping database.Simulation results show that, this method can eliminate the negative effects on RSSI fluctuation as much as possible and provides high ranging precision.Its no environmental limitations and can be applied in range-based localization technique with high value.
