Abstract : The increasing use of mobile technologies last years 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 PDA or mobile phone and wants applications can be improve according to location, weather or any contextual information. However, addressing such context-aware systems deals with three main characteristics: context changes, mobility and limited resources of devices. In this article we respond to user requirements and changes of the environment with dynamic adaptations of application deployment guided by QoS respect. 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, which implements a contextual-deployment heuristic to find a configuration that matches with context and QoS requirements. Kalimucho was tested on the Osagaia/Korrontea component model and the SunSpot platform; results confirm that Kalimucho provides a satisfying execution time to adapt applications.
