The purpose of this project is to design a wireless sensor network. The primary application of this LoRa network is based on the technology used in the country’s rail network in order to monitor the information of railway infrastructures and the network parameters have been selected accordingly. The most important features of this network are its wide coverage, low energy consumption, cheap price and low sending rate. Therefore, the designed network can be used in all similar environments such as applications related to environment, agriculture, geology.
