Abstract

Mobile data synchronization is an important technique used to replicate or synchronize data between a mobile client and a remote server. It helps overcome unstable wireless networks and support the disconnected operation. The current state of mobile data synchronization is most successful at transparently synchronizing all data. Generally, once a synchronization feature enabled, data is automatically synchronized without offering a fine grained and customizable synchronization policy. Furthermore, the context information, such as localization, date, device overload and resource consumption, type and quality of the connection, etc., are not equally taken into account or not considered at all. One solution is to develop a synchronization model that rely on a fine grained and flexible synchronization policy and where context information is considered as first-class citizen. This article puts forward a new model of data synchronization in mobile devices based on progressive data access schema.

2. Setting And Notation

In our setting, we refer to a domain as a finite or infinite collection of values of the same type/category. For example, we may represent the domain of an attributeas a collection of numbers that belong to the interval. Unlike a domain that may be finite, a universe is infinite by definition.
