Revising Transaction Conceptsf or Mobile Computing

It is expected that in the near future millions of users will have access to on-line distributed databases through mobile computers. The restrictions imposed by the nature of the wireless medium and the resulting mobility of data consumers and data producers make traditional transaction models inadequate. In this paper, we investigate means for providing transaction support appropriate for mobile environments. Specifically, we define a model that ensures a weaker notion of consistency, accounts for mobility, and provides for recovery.
