The Smart Parking System network diagram illustrates a modern IoT-based parking architecture. It integrates IR and ultrasonic sensors, Zigbee communication, and ANPR cameras connected through an IoT gateway. Data is processed by an edge server and secured via firewall before being transmitted to the cloud over HTTPS or MQTT. Cloud infrastructure hosts APIs, AI engines, and databases for analytics, payment processing, and mobile app access. Drivers use mobile apps to locate available spaces, while administrators monitor through a secure dashboard. This architecture ensures efficient parking management, real-time space detection, and seamless data flow for smart city environments.
