In the age of pervasive computing, ubiquitous collaboration has become an every-day life paradigm. Without an ideal computing infrastructure, issues with ubiquitous collaboration, such as network unreliability, platform heterogeneity, and client's resource constraints, are inevitable. The traditional replication scheme copes with network unreliability by replicating all the objects of a shared application together at once. This is, however, suitable for neither cooperative applications nor mobile computing devices. These problems can be naturally addressed by using a fine-grained replication scheme that enables a portion of the application objects to be replicated. This paper presents an object-oriented middleware that is capable of dynamically and transparently replicating remotely shared Java applications in a partially and on-demand incremental manner. It is also able to maintain various consistency semantics and enables the coexistence of fine-grained replications and conventional remote method invocations. Empirical results indicate several practical benefits of the middleware.
