Modular Performance Analysis of Energy-Harvesting Real-Time Networked Systems

Abstract—This paper studies the performance analysis problem of energy-harvesting real-time network systems in the RealTime Calculus (RTC) framework. The behavior of an energyharvesting node turns out to be a generalization of two known components in RTC: it behaves like an AND connector if the capacitor used to temporally store surplus energy has unlimited capacity and there is no energy loss, while it behaves like a greedy processing component (GPC) if the size of the capacitor is zero and thus surplus energy is lost or passed to other nodes immediately. In this paper, methods are developed to analyze the worstcase performance, in terms of delay and backlog, of energyharvesting nodes as well as compute upper/lower bounds of their data and energy outputs. Moreover, with the proposed analysis methods, we disclose some interesting properties of the worstcase behaviors of energy-harvesting systems, which provide useful information to guide system design. Experiments are conducted to ev...
