Project Abstract

Built for clear control
over a physical WSN testbed.

Abstract: Creation of a comprehensive user-friendly interface for configuring, programming, monitoring, and analyzing results from a physical WSN testbed. The system provides remote access to testbed functions and visualizes network status.

The interface brings together all aspects of wireless sensor network management — from initial node configuration and firmware deployment, through live telemetry monitoring, to detailed experiment result analysis — in a single, coherent web application.

"This project is a web-based WSN Testbed Management Interface used for configuring, programming, monitoring, controlling, and analyzing wireless sensor nodes in real time."

Technical Architecture

How the complete WSN interface
is designed to work.

React Website UI
Configuration console, live charts, node management, logs, and access control screens
Django REST API
Endpoints for nodes, experiments, deployments, results, users, and authentication
WebSocket Layer
Persistent low-latency channel for live telemetry updates and network status events
Database Layer
PostgreSQL for structured experiment data; MongoDB optional for raw sensor payloads
Hardware Boundary
Serial/USB adapters for gateway connection, node programming, and firmware flashing
Protocols
HTTP REST APIs handle configuration operations and report retrieval, while WebSockets support low-latency telemetry updates during active experiments.
Data Flow
Sensor nodes transmit readings to the gateway via the WSN radio protocol. The backend collects, stores, and processes data, while the interface visualizes current network status and historical results.
Hardware Boundary
Serial/USB operations are isolated in a dedicated module so firmware flashing, telemetry parsing, and gateway communication remain maintainable and independent from the web layer.
Security
Role-based authentication governs all remote testbed access. Administrator, operator, and viewer roles have distinct permission scopes enforced at the API level.
