A collective autonomic system consists of collaborating autonomic entities which are able to adapt at runtime, adjusting to the state of the environment and incorporating new knowledge into their behavior. These highly dynamic systems are also known as ensembles. To ensure correct behavior of ensembles it is necessary to support their development through appropriate methods and tools which can guarantee that an autonomic system lives up to its intended purpose; this includes respecting important constraints of the environment.This State-of-the-Art Survey addresses the engineering of such systems by presenting the methods, tools and theories developed within the ASCENS project. ASCENS was an integrated project funded in the period2010-2015 by the 7th Framework Programme (FP7) of the European Commission as part of the Future Emerging Technologies Proactive Initiative (FET Proactive). The 17 contributions included in this book are organized in four parts corresponding to the research areas of the project and their concrete applications: (I) language and verification for self-awareness and self-expression, (II) modeling and theory of self-aware and adaptive systems, (III) engineering techniques for collective autonomic systems, and last but not least, (IV) challenges and feedback provided by the case studies of the project in the areas of swarm robotics, cloud computing and e-mobility.

Software-intensive systems have become increasingly important for a multitude of products and services from all sectors of the economy, our national and - ternational infrastructure, and our daily lives. The ongoing decrease in size and cost of microprocessorsandstoragedevicesis leading to the development of ever more distributed and decentralized systems. Systems are assembled as dynamic federationsofautonomousandevolvingcomponents insteadof monolithicapp- cations, they perform tasks of staggering complexity with continuously cha- ing requirements and in a permanently evolving environment. In the near - ture novel technologies will allow the construction of systems with millions of nodes,and systems will be likely to containsubsystems basedonnew computing paradigms such as molecular computing. To identify these emergent trends, their impact on the information society in the next 10-15 years, and the challenges they present to computing, software engineering, cognition and intelligence, the European Commission has estab- 1 lished two Coordinated Actions: initially the project "Beyond the Horizon" 2 and then, starting in 2006, the project "InterLink" .Both projects are coor- nated by the European Research Consortium for Informatics and Mathematics (ERCIM EEIG) and funded by the Future and Emerging Technologies (FET) Unit of the European Commission. The ongoing project InterLink is composed of three thematic working groups: software-intensive systems and new comp- ingparadigms;ambientcomputingandcommunicationenvironments;intelligent and cognitive systems. This volume presents the results of the working group on software-intensive systemsandnovelcomputing paradigms.Theobjectivewasto imaginethela- scape in which the next generations of software-intensive systems will operate.

Service-Oriented Computing is a paradigm for developing and providing software that can address many IT challenges, ranging from integrating legacy systems to building new, massively distributed, interoperable, evaluable systems and applications. The widespread use of SOC demonstrates the practical benefits of this approach. Furthermore it raises the standard for reliability, security, and performance for IT providers, system integrators, and software developers.This book documents the main results of Sensoria, an Integrated Project funded by the European Commission in the period 2005-2010. The book presents, as Sensoria's essence, a novel, coherent, and comprehensive approach to the design, formal analysis, automated deployment, and reengineering of service-oriented applications. Following a motivating introduction, the 32 chapters are organized in the following topical parts: modeling in service-oriented architectures; calculi for service-oriented computing; negotiation, planning, and reconfiguration; qualitative analysis techniques for SOC; quantitative analysis techniques for SOC; model-driven development and reverse engineering for service-oriented systems; and case studies and patterns.
