TIRUB: A Safety and Energy-Aware Scheduling Algorithm

The paradigm change towards the Industrial Internet of Things carries considerations related to the implementation and quality of processes already established inside the industries. If we also consider the essential roles that Cyber-Physical systems play in modern industries, we cannot avoid recognizing that devices are obtaining more responsibility. Thus, their safety functioning has to be guaranteed, even if their batteries are running low. The correct scheduling of tasks can provide a functional safety execution, and additionally save energy to ensure that the safety-critical tasks are allowed to run. We present in this paper a novel algorithm named TIRUB, specially designed for the industrial scenario so that devices are compliant with safety standards as the IEC-61508.
