Rejuvenation On-The-Go: Addressing Software Aging in Android Mobile Systems

Abstract:

Both our personal experience and research experiments tell us that mobile systems, such as the Android OS, are affected by software aging. Restarting apps or rebooting can address aging, but at the cost of poor user's perception of quality of the mobile device. This talk will present recent work on software rejuvenation for the Android OS, based on measurement-based and micro-rejuvenation techniques, for reducing impact on availability.

Title:

Software Rejuvenation and Cybersecurity Issues in Model Predictive Control

Abstract:

Model predictive control (MPC) schemes have become a popular choice for multiple applications, including networked control problems. However, schemes have been developed naively, presenting flaws and vulnerabilities that malicious entities can exploit to gain leverage in cyber-attacks. The goal of this talk is to raise awareness about this issue by reviewing the vulnerabilities of MPC methods and surveying defense mechanisms, very particularly Software Rejuvenation (SR). Finally, several possibilities to combine SR and MPC to deal with cyber-security threats will be examined.
