A Configurable Software Aging Detection and Rejuvenation Agent for Android

This paper presents the design of ADaRTA, an aging detection and rejuvenation tool for Android. The tool is a software agent which i) performs selective monitoring of system processes and of trends in system performance indicators; ii) detects the aging state and estimates the time-to-aging-failure, through heuristic rules; iii) schedules and applies rejuvenation, based on the estimated time-to-aging-failure. The agent rules and parameters have been defined for ease of configuration and tuning by device designers. A stress testing experiment is discussed, showing ADaRTA’s configurability for the device under test, and the ability of detecting the aging state to prevent device enter a failure state.
