Pervasive Grid applications solve complex tasks in distributed environments relying on centralized and decentralized nodes interconnected by wireless and wired networks.

Abstract
Pervasive Grid applications solve complex tasks in distributed environments relying on centralized and decentralized nodes interconnected by wireless and wired networks. Examples of such applications are Emergency Management and Intelligent Transportation. In previous works we introduced the ASSISTANT programming model as a support for easy and efiective development of pervasive Grid applications. In this work we extend ASSISTANT in order to support fault tolerance. This is done by providing constructs enabling and controlling replication. Via these constructs, the application programmers can express replication strategies, which are automatically managed by the ASSISTANT run-time sup port in terms of replica consistency. We also report some experimental results showing reduced performance overheads for the classical case of replica consistency relying on a-priori agreement on the processing order of input streams in case of a ood emergency management application.
