An Earthquake Monitoring System of LoRa Dynamic Networking Based on AODV

In recent years, earthquake disasters are increasingly frequent, resulting in great loss to people’s life and property. In order to better evaluate and predict the earthquake, it is of great significance to design a system which can effectively collect the seismic data when an earthquake occurs. LoRa wireless communication has the advantages of low power consumption, long communication distance and strong anti-interference ability. In this paper, LoRa network is used to upload the data collected by the seismic sensor to the LoRa base station. Then, the data is sent to the cloud server through 4G, finally received by the working platform. In view of the node damage during the earthquake, the AODV protocol is used to ensure the transmission of acquisition data in the form of dynamic networking. The result shows that the monitoring system of LoRa network seismic monitoring system based on AODV protocol runs stably and can obtain reliable seismic data.
