Recently, the increasing use of mobile technologies leads to face to new challenges in order to satisfy people using mobile devices. As they use their favorite applications on their personal computer at home, people wants to use it on their smartphone or tablet and wants applications to be improved according to GPS position, weather or any contextual information. However, addressing such context-aware systems deals with three main characteristics: context changes, mobility and limited resources of such devices. In this article we try to address such requirements using QoS-driven dynamic adaptations of application deployment. We are particularly interested in distributed applications QoS management facing with hardware limitations and mobility of devices, user requirements and usage constraints. We propose a service-based reconfiguration platform named Kalimucho. It implements a contextual-deployment heuristic to find a configuration matching context and QoS requirements. Kalimucho was tested with the Osagaia/Korrontea component model and several devices; the results confirm that Kalimucho provides a satisfying execution time to adapt applications.
