RSquare: Scalable IoT Tracker Platform

RSquare is a cloud-based IoT solution architected to address modern device connectivity and alerts management. The system design focuses on scalability, flexibility, and ease of use, allowing seamless integration of remote sensor nodes. The architecture ensures that users can effortlessly monitor and configure their devices, with real-time SMS and push notifications providing critical alerts and event updates to keep users informed.
The solution utilizes a robust tech stack, with AWS IoT Core at the heart of device communication. AWS Lambda and Serverless (Node.js) are used for scalable, event-driven backend processing, while PostgreSQL ensures reliable and efficient data storage. Twilio and Mailgun handle SMS and email notifications, and Auth0 provides secure user authentication. The system leverages AWS CloudWatch for monitoring and logging, ensuring full visibility into operations.
The proposed architecture incorporates a hybrid protocol strategy, combining CoAP, MQTT, and REST to optimize communication between edge devices. This approach maximizes energy efficiency, ensuring long-lasting battery life while communicating over LTE networks.
The entire architecture was validated through several small proof of concept projects to confirm its reliability and performance under real-world conditions. Following this validation, the architecture was thoroughly documented to ensure clear implementation and provide a reference for future development and scalability.
