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 {\textquoteleft}{\textquoteleft}Adaptation as a Service{{\textquoteright}{\textquoteright}} layer into basic cloud architecture, to perform the correct execution of transactional service according to the user context.}, isbn = {978-1-4673-8149-9}, author = {Ettazi, Widad and Hafiddi, Hatim and Nassar, Mahmoud and Ebersold, Sophie} } @conference { ISI:000377500700024, title = {MiCATS: Middleware for Context-Aware Transactional Services}, booktitle = {ENTERPRISE INFORMATION SYSTEMS (ICEIS 2015)}, series = {Lecture Notes in Business Information Processing}, volume = {241}, year = {2015}, note = {17th International Conference on Enterprise Information Systems (ICEIS), Barcelona, SPAIN, APR 27-30, 2015}, pages = {496-512}, publisher = {Inst Syst \& Technol Informat Control \& Commun; Assoc Advancement Artificial Intelligence; IEICE Special Interest Grp Software Enterprise Modelling; ACM Special Interest Grp Management Informat Syst; ACM Special Interest Grp Artificial Intelligence; Asocia}, organization = {Inst Syst \& Technol Informat Control \& Commun; Assoc Advancement Artificial Intelligence; IEICE Special Interest Grp Software Enterprise Modelling; ACM Special Interest Grp Management Informat Syst; ACM Special Interest Grp Artificial Intelligence; Asocia}, 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.}, isbn = {978-3-319-29133-8; 978-3-319-29132-1}, issn = {1865-1348}, doi = {10.1007/978-3-319-29133-8\_24}, author = {Ettazi, Widad and Hafiddi, Hatim and Nassar, Mahmoud and Ebersold, Sophie}, editor = {Hammoudi, S and Maciaszek, L and Teniente, E and Camp, O and Cordeiro, J} }
