Design and implementation of IOT system based LoRa

Abstract

The internet of things (IOT) is one of the most growing technologies in the last few years. However, this technology increases the demand for connected devices. Various standards are currently contending to gain an edge over the competition and provide the massive connectivity that will be required by a world in which everyday objects are expected to communicate with each other. Among these standards, Low-Power Wide Area Networks (LPWANs) are continuously gaining momentum, mainly thanks to their ability to provide long-range coverage to devices,exploiting license-free frequency bands. LoRa is emerging as one of the most promising LPWAN, since it enables the energy-constraint devices distributed over wide areas to establish affordable connectivity. However, how to implement a cost-effective and flexible LoRa network is still an open challenge. This project aims to design and implement a prototype for a low cost LoRa network for IOT application. The network prototype will be designed based on the five-layer conventional IOT architecture. Our design will include hardware and software implementation of a LoRa end node, single-channel LoRa gateway and a network server. Furthermore, we implement a new transmission protocol between the end node and the gateway based on the variation of the LoRa module parameter. In addition, our implementation also includes a data handling system that collects the data from the network server and save it to the cloud.
