RFID Edge Server Non-blocking I/O and Data Filtering

The patent replaces traditional blocking I/O mechanisms with asynchronous non-blocking I/O operations. The server uses non-blocking socket operations combined with event-driven programming models to handle RFID reader communications, eliminating the need for CPU-intensive blocking waits and enabling concurrent processing of multiple reader connections without additional threads.

The patent introduces an event loop as an intermediary between the non-blocking I/O operations and the application logic. This event loop continuously monitors file descriptor states, manages the event queue, and dispatches appropriate handlers, serving as a mediator that coordinates asynchronous I/O operations while maintaining system responsiveness and efficiency.

The patent extracts and removes duplicative data elements from the RFID reader responses before forwarding to the central server. The edge server implements intelligent filtering logic that identifies and eliminates duplicate EPC readings, redundant event notifications, and redundant data based on comparison with previously received data, thereby reducing network traffic and processing requirements while preserving unique and valuable information.

The patent applies local quality optimization by implementing context-aware filtering at the edge server location. The filtering logic adapts to local conditions such as reader identification, tag frequency, and data patterns specific to each deployment scenario, enabling intelligent differentiation between necessary and redundant data transmissions based on local operational characteristics.
