X-Leep: Leveraging Cross-Layer Pacing for Energy-Efficient Edge Systems

Edge systems enable large numbers of embedded nodes to communicate in order to cooperate towards achieving a shared goal. However, such systems operate under both timeliness and energy-efficiency constraints. This paper proposes X-Leep, a run-time system that detects the pace of the system, supporting Internet-of-Things and Edge scenarios. X-Leep adapts the local processing speed accordingly, considering time-related and energy-related constraints. Our evaluation shows that X-Leep increases energy efficiency compared to state of the art with only a minor effect on the quality of service.
