Special Issue on
Software Architectures for Smart and Adaptive Systems (SASAS)
in the Information and Software Technology Journal

This special issue on Software Architectures for Smart and Adaptive Systems (SASAS) 
aims to outline the importance of the architectural aspects in the development of 
dynamic software solutions for organizations, and their role in ensuring and improving 
the overall quality of the software. 

Smart and adaptive solutions are aware at run-time of their execution environment 
and of their internal structure and behavior. Further, they exploit this awareness 
to adapt reactively, proactively, predictively, and intelligently to the context 
and to provide smart and enhanced services that meet the users' needs and ensure 
the required and expected quality. In smart and adaptive systems, the decision 
process tends to move from design to run-time, where the context plays a key role 
in the system behavior. This shift from the design to run-time is mostly due to the 
uncertainties triggered by changes in the execution environment, the behavior of 
the users, or the changes in the requirements which cannot be anticipated during 
the development phase. Therefore, a smart and adaptive system should be able to 
address and manage these uncertainties based on the available knowledge about itself 
and its execution surroundings. Software is expected to make wise use of this 
knowledge at run-time. An important challenge is related to the provision of 
guaranties for such systems potentially exposed to continuous uncertainties.  

The complexity of smart and adaptive software is increasing every day, due also 
to the inclusion of various methods taken from areas different from pure software 
engineering, such as Artificial Intelligence, Industry 4.0 just to mention two 
common examples. Thus, software asks for innovative and enhanced engineering, 
maintenance, and evaluation approaches and practices to address the continuously 
changing requirements and expectations of the IT and business world, as well as 
the evolution of the available solutions. In this context, software architecture 
defines the basic blocks to prepare and ensure the quality attributes of a system. 

This SASAS special issue calls for contributions that identify and describe the 
issues and challenges raised by the development and the evolution of software systems 
that are context-aware, dynamic, distributed, autonomous, smart, adaptive, 
mobility-enabled, and self-managed from an architectural perspective. 
The software architecture establishes the fundamentals and the rules for the interaction, 
integration, communication, observation, and control aspects that should be addressed 
during the software development and maintenance phases. Furthermore, the special issue 
welcomes contributions concerning available research and industrial case studies and 
solutions, lessons learnt, addressed as well as open challenges in designing and 
developing software architectures for context-aware smart systems. 

We call for original previously unpublished research and industrial papers. Further, 
we encourage the submission of extended versions of papers presented at the 
Workshop on Context-aware, Autonomous, and Smart Architectures 
(CASA 2020 - https://casaecsa.github.io/casa2020/) co-located with the 
14th European Conference on Software Architecture (ECSA 2020).
