What about collaboration in ubiquitous environments?

Smart Buildings have been the subject of research for more than two decades. The different perspectives range from monitoring and controlling energy consumption. Indeed, energy efficiency is considered as one of the promising fields of applications of the Internet of Things. Since Smart Buildings are an important part of the smart grid, their energy efficiency is vital for the environment and global sustainability. In ubiquitous computing systems, designing Smart Building applications is a challenge since these applications must ensure a trade-ofT between energy consumption and occupants comfort especially in ubiquitous environments. In this paper, we focus on the design of a Smart Building application in ubiquitous computing systems. TheSmart Building application is able to manage energy consumption while keeping the occupants comfort. We elaborate an illustrative scenario to demonstrate the usefulness of our work.

While maintaining core assets of a product line, product line engineers may need to adapt the assets to accommodate new requirements and new devices from the changing and newly emerging markets. Additionally, due to the emergence of new computing environments like autonomous systems (e.g., ubiquitous computing and the Internet of Things), there is increasing demand for dynamic adaptations of core assets, and this often needs to be managed with minimum human intervention. We propose an approach for managing a distributed feature model in order to facilitate the adaptation of self-adaptive dynamic software product lines (DSPLs). In addition, our approach allows the change of behaviours to promote the long lifecycle of self-adaptive DSPL. The case study applied in this paper is a baby care system (BCS). BCS assists people to monitor a baby while they are sleeping. We tested our BCS in the following scenarios: adding features, removing features and changing behaviours. All these scenarios showed that it is possible to use our approach to self-adapt DSPLs.

“…Most of the approaches in the pervasive computing literature mainly focus on tasks of individual users, and provide very limited support to collaborative tasks of a group of actors 7 . Furthermore, existing approaches in developing collaborative pervasive applications (e.g., 8,9,2,3,10 ), and middleware architectures and frameworks for pervasive computing 11 are limited in supporting the dynamic relationships between actors, which themselves are an important aspect of context.…”

We present a social context as a service (SCaaS) platform for managing adaptations in collaborative pervasive applications that support interactions among a dynamic group of actors such as users, stakeholders, infrastructure services, businesses and so on. Such interactions are based on predefined agreements and constraints that characterize the relationships between the actors and are modeled with the notion of social context. In complex and changing environments, such interaction relationships, and thus social contexts, are also subject to change. In existing approaches, the relationships among actors are not modeled explicitly, and instead are often hard-coded into the application. Furthermore, these approaches do not provide adequate adaptation support for such relationships as the changes occur in user requirements and environments. In our approach, inter-actor relationships in an application are modeled explicitly using social contexts, and their execution environment is generated and adaptations are managed by the SCaaS platform. The key features of our approach include externalization of the interaction relationships from the applications, representation and modeling of such relationships from the domain and actor perspectives, their implementation using a service oriented paradigm, and support for their runtime adaptation. We quantify the platform's adaptation overhead and demonstrate its feasibility and applicability by developing a telematics application that supports cooperative convoy.
