Link Quality Analysis for Buried Pipeline Monitoring using LoRa

This work focuses on the analysis of link quality in the context of monitoring buried pipelines using wireless underground sensor networks. The study examines three communication channels: pipe to ground, ground to pipe and in-pipe. The investigation considers factors such as burial depth and the material of the pipe. Various metrics, including received signal strength indicator, signal-to-noise ratio and packet delivery ratio, are observed and analyzed for all the communication channels. The experimental investigation conducted at a frequency of 868 MHz using LoRa technology reveals strong signal strength and reliable communication across the three communication channels.
