The Localization Algorithm Based on On-Line Training RSSI in WSNs

摘要：

The off-line training RSSI localization algorithm isonly fit to the position where it has been trained before andwhenever the condition of the environment changes,theprogram in the hardware must be reprogrammed,so thealgorithm has a poor adaptability under different environmentsand leads to a certain limitation to the applications in someprojects.Combined with the rough-precision TOA,a newmethod called on-line training RSSI localization algorithm hasbeen formed.It can adapt to any kinds of conditions and canachieve a more accurate position without a high hardwareconfiguration.The simulation results also show that thisalgorithm has improved its performance in resistance to the.noise.
