Disconnection Metadata for Distributed Applications in Mobile Environments

The need to continue to work in a mobile environment raises the problem of data availability in the presence of disconnections. Our approach aiming at solving this problem is to make a local replication of data and code on the mobile terminal. The system and the applications should also be reactive to mobile environment changes. The work presented in this paper is the continuation of Domint [6, 7], a platform to cope with disconnections in mobile environments for CORBA-based applications. In this paper, we go further in the study of the role of disconnected entities by proposing meta-data to build patterns in order to (1) choose which entities of the distributed application must become disconnected, and (2) state whether disconnected entities are necessary for the execution while being disconnected. We also outline the integration of these meta-data into the CORBA component-based architecture.
