        LoRaWAN Mesh Network for Long-Range Environmental Monitoring

         

        Abstract

        In this project, we engineered a sophisticated LoRaWAN-based mesh network designed to facilitate long-range, low-power communication between multiple distributed sensor nodes and a centralized gateway system. The architecture was developed to transmit high-fidelity temperature and humidity data from sensor nodes to a cloud-based database utilizing LoRaWAN technology in conjunction with Firebase Realtime Database for robust data storage and visualization. This comprehensive setup enables real-time remote monitoring with broad applications in smart agriculture, environmental monitoring, and intelligent building automation systems.


        Background and Motivation

        LoRa (Long Range) is a modulation technique based on Chirp Spread Spectrum (CSS) technology, which allows for low-power communication over distances up to 15 kilometers in rural areas. LoRaWAN (Long Range Wide Area Network) is a communication protocol and system architecture that extends LoRa by defining the network layers above the physical layer, enabling secure bi-directional communication, mobility, and localization services.

        Traditional point-to-point communication systems are limited in range and scalability, especially in environments where infrastructure is sparse or nonexistent. Mesh networking over LoRaWAN addresses these limitations by allowing nodes to relay messages through neighboring nodes, effectively extending the network’s coverage and enhancing reliability through redundant paths. This mesh topology is particularly advantageous in remote monitoring applications, where sensor nodes may be dispersed over large geographical areas with challenging terrain.

        The motivation for this project stemmed from the need to explore and leverage the capabilities of LoRaWAN mesh networks for real-time environmental monitoring. By integrating low-power sensors with long-range communication and cloud-based data management, we aimed to create a scalable and energy-efficient system capable of operating in remote or hard-to-reach locations without the need for constant human intervention or infrastructural support.
