Cooperative Discovery of Failed IoT Node by Double-Zone Presentation
Rui Teng · 2024
Maintaining the functionality of Internet of Things (IoT) nodes such as sensors is essential for the sustainability of IoT. The long-term failure of IoT nodes requires quick discovery and recovery. In this paper, we address the issue of identification of the failed IoT node that lacks location information. We proposed a scheme of double-level presentation of failure for guiding the maintaining robot to find the failed node. Evaluation results show that the proposed method efficiently reduces the search times and robot-movement distances in discovering the failed IoT node.
