The data is most important thing for analysis to predict the next event. As internet of things comes into the application, accuracy and synchronization is necessary for real time IoT application. In this paper the readings has taken from IoT based vibration sensor which has placed besides the road to sense vibration of the vehicles. The sensor hub is transmitting the sensors values to the receiver. For transmission of sensors values to receiver hubs end if send time, access time, propagation time and receive time vary or delayed then it can be reduced by the following proposed system for the synchronization. Here, the DFT is used for the calculation of the signals frequency spectrum for synchronisation and DWT is used for sampling of the signal received by the transmission hub.

IoT, DFT, DWT, NTP, UTC, TPSN, RBS and PSD.
