The Internet of Things (IoT) is an emerging paradigm where practically every (physical and virtual) thing will be interconnected through innovative distributed services. Since the number of connected things is rapidly growing, IoT systems will require the composition of plenty of services into complex workflows. Thus, scalability in terms of the size of IoT systems becomes a significant concern. In this paper, we review and evaluate the fundamental semantics of existing IoT service composition mechanisms to determine how well they fulfil the scalability requirements of IoT systems. We identify scalability desiderata and, accordingly, our findings show that dataflows, orchestration and choreography do not fully satisfy such desiderata, unlike a novel composition mechanism called DX-MAN.

“…ULSS is a socio-technical ecosystem and involves people, policies, cultures and economies in addition to large-scale software intensive systems [12]. Although many authors believe that ULSSs are more complex and challenging than SoSs [24][29] [32], some of them discuss that ULSSs inherit characteristics of SoSs, therefore have some characteristics in common with today's SoSs [26] [32]. Hence in this paper considering the characteristics and taxonomy of both types of systems would be helpful.…”

Abstract-Software applications play a major role to support the smartness in Smart Grid. Such applications are in a neverending state of flux due to rapidly changing expectations from the users and stakeholders. Hence, evolution is an important matter for development of Smart Grid software applications and the challenging factors of software evolution in Smart Grid should be identified. This position paper presents a discussion on the Smart Grid software applications as an ultra-large-scale system, focusing on the possible challenges that need to be addressed for an effective and efficient evolution of the area.Index Terms-Smart Grid, software applications, software evolution, systems of systems, ultra-large-scale system.

“…The development of large software systems is another area of interest that has been, for decades, subject of research work; several topics can be pointed out such as the exploration of issues related to the management of large scale software development [6,7], software architecture [8][9][10], model-driven development [11,12], among others. Not directly related with large projects, Medvidovic [13] points the relevance of software architecture in leveraging the pervasive and ubiquitous area.…”

Abstract. Pervasive computing is a research field of computing technology that aims to achieve a new computing paradigm. Software engineering has been, since its existence, subject of research and improvement in several areas of interest. Model-Based/Driven Development (MDD) constitutes an approach to software design and development that potentially contributes to: concepts closer to domain and reduction of semantic gaps; automation and less sensitivity to technological changes; capture of expert knowledge and reuse. This paper presents a profiling and framing structure approach for the development of Pervasive Information Systems (PIS). This profiling and framing structure allows the organization of the functionality that can be assigned to computational devices in a system and of the corresponding development structures and models, being. The proposed approach enables a structural approach to PIS development. The paper also presents a case study that allowed demonstrating the applicability of the approach.Keywords: MDD, PIS, pervasive, ubiquitous, software engineering, process, information systems, architecture, framework. IntroductionThe dissemination of computing and heterogeneous devices and platforms, the high pace of technological innovations and volatile requirements, the size and complexity of software systems characterize the software development context today. This context challenges the way software is developed for emerging forms of information systems. Software Development Processes (SDPs), as well as generalized adoption of models, are fundamental to efficient development efforts of successful software systems. Pervasive Computing, also called Ubiquitous Computing [1,2], represents a new direction on the thinking about the integration and use of computers in people's lives. It aims to achieve a new computing paradigm, one in which there is a high degree of pervasiveness and availability of interconnected computing devices in the physical Profiling and Framing Structures for Pervasive Information Systems Development 285 environment. Widespread availability of affordable and innovative information technologies represents a potential opportunity for improvement/innovation on business processes or for enhancement of life quality of individuals. Among other things (such as social concerns), this opportunity promotes the attention to the efficiency and effectiveness of information management regarding to the way they acquire, process, store, retrieve, communicate, use, and share information. To take full benefits of the opportunities offered by modern information technologies, these devices need to be "appropriately integrated within organizational frameworks" [3]. Therefore, Pervasive Information Systems (PIS) [4] orchestrate these devices in order to achieve a set of well-established goals. In this way, PIS not only provide a solid basis to sustain the needed information to achieve effectiveness at both individual and organizational levels, but also leverages the investment on those information techno...
