Use of Wireless LoRa Technology in Flood Early Warning Systems

Abstract

Wireless communication is paramount for effective environmental monitoring and disaster preparedness, particularly in remote and flood-prone regions. This paper investigates the application of Long Range (LoRa) technology as a robust and efficient solution for Flood Early Warning Systems (EWS). We delve into LoRa’s fundamental characteristics, including its extended range, low power consumption, and resilience to interference, which make it uniquely suited for deploying sensor networks in challenging geographical areas. The paper details the typical architecture of a LoRa-based EWS, encompassing remote 
sensing nodes, repeaters, and a central receiver, and discusses key operational parameters such as carrier frequency, transmit
power, and data packet configurations. Furthermore, we explore essential security measures, including AES-128 encryption and
authentication mechanisms, to ensure data integrity and confidentiality. Through a generalized examination of its deployment,
this paper demonstrates LoRa’s efficacy in facilitating realtime data collection for hydrological parameters, enabling timely
data access and enhancing community resilience against natural disasters.
