De-Fence: LoRa based Hop-to-Hop Communication

The need for a low-power reliable form of communication is ever-present in a multitude of fields. Our paper aims to develop and explore a security-oriented application of LoRa-based hop-to-hop communication, which provides low-power, large-scale, and long-range solutions to our current safety needs. It utilizes all the components of an IoT-based implementation, in to develop a network, which consists of different types of nodes. It takes input from the external environment through sensors, transports it via several intermediate nodes, using an effective routing algorithm, and provides output through the means of an actuator. The system achieved henceforth is highly scalable, reliable, portable, cheap, and easy to maintain, and provides a fresh outlook on the contemporary need of modernizing the security infrastructure using a growing non-cellular form of communication, LoRa technology.
