An Enhanced Approach for RFID Reader Deployment in Industrial IoT Systems with Collision Avoidance and Optimized Coverage

This paper introduces an innovative approach to tackle the issue of radio frequency identification (RFID) reader-coverage collision avoidance deployment in industrial Internet of Things (IoT) systems. The primary objective of our proposed methodology is to enhance the dependability and reliability of reader deployment. To accomplish this, we present a deterministic algorithm that divides the target field into grids and identifies interlaced positions as potential deployment locations for readers. Additionally, we evaluate the coverage weight of tags for each position and strategically choose the position with the highest weight to deploy a reader. This iterative process continues until all tags are adequately covered by readers. Furthermore, we optimize the reading range of each reader by considering its adjustable range capability, thus ensuring efficient and reliable tag coverage while minimizing potential interference among readers.
