🚲 VeloSync – Smart Geolocation-Based IoT Bicycle Sharing Platform

📖 Project Overview

VeloSync is a smart, map-based Progressive Web App (PWA) for bicycle sharing.

It allows users to find, reserve, unlock, ride, and return bicycles using virtual geofenced stations without requiring expensive physical docking stations.

The project combines web technology, geolocation, IoT, and spatial databases to provide a secure and efficient bicycle-sharing system.

✨ Key Features

• 📍 Virtual Geofencing – Defines authorized bicycle parking areas.
• 🔵 Offline Web Bluetooth – Allows communication with the bicycle through BLE when internet connectivity is unavailable.
• 🚲 Smart Bicycle Sharing – Find, reserve, unlock, and return bicycles.
• 🔄 Fleet Rebalancing – Encourages users to move bicycles between stations using rewards.
• 📱 Progressive Web App – Works directly through a web browser without requiring a traditional app installation.
• 🔐 Secure Authentication – Uses JWT-based authentication.
• ⚡ Concurrency Control – Prevents multiple users from booking the same bicycle.
