	abstract = {Advances in wireless communications and mobility have increased the use of smart mobile applications. As a result of the remarkable increase of mobile devices and the pervasive wireless networks, a large number of mobile users are requiring personalization services customized to their context. The mobile cloud-computing paradigm from a context-aware perspective aims to find effective ways to make cloud services aware of the context of their customers and applications. Another major challenge for context-aware cloud services is to exploit the benefits of cloud computing to manage transaction processing throughout the life cycle of a service. In this paper, we focused on the need of loosely coupled context-supporting components that work with a transaction-aware service infrastructure to adapt services to the context of the user and his mobile device. We propose a cloud-based middleware for transactional service adaptation (CM4TSA) by adding the "Adaptation as a Service" layer into basic cloud architecture, to perform the correct execution of transactional service according to the user context. {\textcopyright} 2015 IEEE.},

	abstract = {In context-aware service-based environments, fulfilling user{\textquoteright}s recommendations bring about several challenges that are mainly due to the dynamic nature and limited underlying resources of these environments. In this paper, we mainly focus on the transactional aspects of context-aware services. To cope with the aforementioned issues, we opt for a middleware-based solution (MiCATS). We therefore present our novel approach for managing context-aware transactions which allows for adaptation to the requirements of applications and mobile context in terms of transactional properties. Then, we introduce our context-aware transactional service model (CATSM) and a context-aware architecture based on adaptation policies. The proposed contributions are implemented within a middleware platform. {\textcopyright} Springer International Publishing Switzerland 2015.},

	abstract = {One goal of ubiquitous computing is to enable users to access and perform transactions from any location, at any time and from any device. In a context-aware environment, transaction management is a critical task that requires a dynamic adaptation to the changing context in order to provide service reliability and data consistency. In this paper, we propose a new approach for managing context-aware transactional services. Then we discuss the various researches that have addressed this issue. Finally, we propose a new model for the adaptability of context-aware transactional services called CATSM (Context-Aware Transactional Service Model) and the adaptation mechanisms to implement this model.

	abstract = {Today, information systems are radically marked by considerable progress in the areas of software engineering, telecommunications and ubiquitous computing. This has led to the development of new interaction pattern where the service oriented architecture is the de facto pattern. In this article, we are particularly interested in transactional services. We position our approach in the context of a user-centered model driven engineering (MDE) approach in order to move from one perspective where models were contemplative artifacts to a perspective where they become productive artifacts. For this, we first present our approach for managing context-aware transactional services (CATS). Then, we propose a CATS specification and metamodel. The adaptation mechanism is also detailed in this paper. {\textcopyright} Springer International Publishing Switzerland 2015.},
