LoRa communication and geolocation system for sensors network

Abstract

The Internet of Things (IoT) has developed tremendously over the past few years and has proven its worth in many areas of activity. With regard to environmental air quality monitoring, there are more and more products and applications that try to gather as much data as possible about all the pollution factors in a given area. This paper aims to present a new method of using devices capable of communicating with each other using the LoRa communication protocol to report to a real-time central server on environmental air quality. The innovation of this paper is the fact that it is implemented using a developed LoRa localization protocol, which connects an air quality sensor network, using only the low power of the LoRa technology by applying a multilayer algorithm to the gateway timestamps from received packages. The so created LoRaWAN tracking system is able to exploit transmitted packets to calculate the current position without using GPS or GSM that are high power consumers.

LoRa Network Planning and Deployment: A Terrestrial Navigation Application

“…The work by [22], specifically deals with how LoRa could be used to determine location of a node using stationary gateways and three different methods. However, it is unclear how accurate their position solutions are nor is it clear if gateway to gateway geometry can help enhance or worsen the position accuracy of a node.…”

“…2019 0 [22] This article discusses three methods of localisation using LoRa and discusses the feasibility of the methods based on the computational requirements. Specifically, the authors explore trilateration, multilateration and hyperbolic multilateration methods in unison with the angle of arrival (AoA), time of arrival (ToA) and time difference of arrival (TDoA) respectively.…”

Autonomous Control System for an Electric ATV

“…LoRaWAN is perfect for endpoints with wireless communication and battery power from an IoT network, being able to provide secure two-way communications at different data transfer speeds. Typical applications of LoRaWAN are sensors networks, security systems, smart homes, smart metering devices, industrial control and smart cities [15]. The range of 2-5km in urban areas and up to 15km outside is possible through a balance between the range of communication and the duration of the message over a broad spectrum at sub-GHz frequencies, and an adaptive speed scheme of data transfer.…”
