Résumé : The mobile phone technologies are becoming pervasive in recent years. These items such as IPhones, IPad and Andro¨ıds are very attractive since they provide relatively good resources for a mobile device. Several works aim at integrating desktop applications in these tools to make them closer to the real computer. However, adapting desktop applications to these tools is a challenging problem as they do not have the same features. Real time collaborative editors are famous applications allowing for several users to edit the same shared document simultaneously. Such an application is more and more used not only in professional fields but also in a personal context. In this work, we extend decentralized collaborative editors to mobile devices by conceiving a successful garbage collection scheme that optimally manages mobile devices resources. We propose a novel design for distributed garbage collection that ensures a good behavior of the application through the good measurements obtained for different types of mobile phones.
