ABSTRACT
LoRa technology has brought significant improvements in terms of range and resistance to interference, which has significantly expanded the field of application of wireless sensor networks (WSN) to larger geographical areas. Time synchronization is a significant problem in WSN since it is necessary to synchronize the local clocks of a large number of sensor nodes with sufficient accuracy. Since communication in WSN is performed at low data rates and nodes spend a lot of time in a low-power modes, it becomes challenging to maintain time synchronization between nodes under such conditions. This paper presents the method of time synchronization between WSN network nodes using LoRa technology, and based on measurements, the expecte synchronization accuracy is determined in the case of crystal resonators and crystal oscillators, which are most often used as clock sources in WSN nodes.
