Adaptive systems can respond to environmental changes including hardware/software defects, resource changes, and non-continual feature usage. As such, adaptive systems can extend the area of operations and improve efficiency in the use of system resources.
However, adaptability also incurs overhead in terms of system complexity and resource requirements. For example, an adaptive system requires means for reconfiguration that allows it to adapt to changes. These means and their mechanisms introduce additional complexity to the design and the architecture, and they also require additional resources such as computation, power, and for distributed reconfiguration also communication bandwidth.
Moreover, to take advantage of adaptability, new specification methods are needed, to define acceptable adaptation ranges which will be explored by the system at run-time to improve a given performance metric. However, current operating systems and network protocols are not designed to support such flexible requirements, and generally do not support complementary reflexive mechanisms that are needed to allow the application to adjust itself to the current configuration.
Finally, programming such systems also needs adequate middleware layers that provide adequate interfaces for the development of adaptive applications. Building such middleware so that it preserves adaptability while providing performance guarantees together with satisfying other usual goals, such as modularity, reusability and scalability, is a challenge still to be conquered.
The objective of the 4th Workshop on AdaPtive and Reconfigurable Embedded Systems
(APRES 2012), held in conjunction with the CPSWEEK'12, in April 16, 2012, Beijing, China, is to foster discussion on new and on-going research in the development and use of adaptive and reconfigurable embedded systems and gather feedback from the embedded systems community at large. Of particular interest are new concepts and ideas for modeling and analyzing tradeoffs of embedded and real-time systems, novel algorithms and mechanisms to realize adaptation and reconfigurability, and experience reports with practical or industrial case studies.
This special issue includes eight selected papers from APRES 2012, which address issues so diverse as GPU resource management, resource management for virtualized systems and adaptive control applications, energy management in adaptive systems, development of SOA using model-driven approaches, the use of timed automata for model and analysis of adaptive embedded systems and resource provisioning for wireless sensor and actuator networks.
In addition, the workshop also included an invited talk, entitled “Network Challenges in Cyber-Physical Systems”, given by Luis Almeida. The talk addressed the requirements of emerging CPS applications, with focus on the combination between openness and timeliness guarantees.
The workshop was partially supported by the Portuguese Government through FCT - “Fundação para a Ciência e a Tecnologia” in the scope of project Serv-CPS -PTDC/EEA-AUT/122362/2010.
