“…In 1997, the US Defense Advanced Research Project Agency (DARPA) referred to self-adaptive software as one that evaluates its own behavior when the evaluation shows that it cannot achieve what the software was supposed to do, or when improved functionality or performance is possible [31]. Adaptive mechanisms and self-awareness have also been applied to hardware [32], [33]. Razor, a general-purpose processor, reduces its operating voltage until it produces an erroneous result [32].…”

Cyber-Physical Systems (CPSs) are large-scale complex systems that monitor and control physical processes by using computer algorithms tightly integrated with networking and their users. Monitoring and controlling the physical environment is a hot topic for today's researchers and engineers in academia and industry. Within this realm, an important feature of current and future Information and Communications Technology (ICT) systems is self-adaptation-yet there is a shortage of information focusing on this characteristic in the literature, particularly as it relates to CPSs. Here, we investigate current state-of-the-art research on CPSs from this perspective, and evaluate the main self-adaptive approaches proposed in the literature, along with their results, strengths, and weaknesses. We also discuss appropriate techniques for enabling self-adaptation capabilities within CPSs at different architectural layers. Overcoming the challenges associated with designing and implementing self-adaptive mechanisms in CPSs will provide a path for bolstering a new generation of CPSs with greater robustness and reliability.
