RESUMO

Pervasive Computing is a new paradigm that states that the computational environment must be available to the user at any time and location. In this scenario, the applications are widely distributed, mobile and hosted on inherently open and dynamic environments. Moreover, the systems must have mechanisms that enhance the cooperation among users as well as among applications. These features strengthen the challenges related to the execution infrastructure for distributed systems and add new aspects that need to be considered. Existing coordination models employed in distributed systems are limited considering the demands of modern computing environments, specially regarding scalability, mobility and disconnection. This work presents the EXEHDA-TS, which is a distributed mechanism for coordinating applications in the Pervasive Computing with dynamic control of scalability and communication costs. The proposed software architecture allows a proactive coordination and information exchange among components of distributed applications, promoting scalability in a mobile environment. The EXEHDA-TS was modeled as a service and implemented as a prototype running on the pervasive environment managed by the middleware EXEHDA. The prototype was evaluated through case studies of the medical field, considering the challenges inherent to the project PERTMED, and it accomplished the requirements of the focused scenarios
