In this paper we show an algorithm for dynamic reconfiguration of distributed applications based on the mobile agent model. We also show that the proposed algorithm can be easily implemented in the IPL language, a language with several abstractions for…

This paper presents an evolution of a simulation environment where situations in which a DDB should maintain data integrity are modeled and implemented. These situations include failures taking place during transactions, and the focus is mainly on the utilization and…

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel perfor-mance against the local interactive response. Explicit and implicit coscheduling techniques in a…

This work presents the development of an instantaneous messaging system, which is centered on the distributed handling of user groups. The method pro-posed for handling of groups has several distinctive characteristics: the non exis-tence of a moderator for each group,…

When certain enterprise domain needs to make an unusual decision, it will probably require new kind of information. If the interaction model among domains cannot be defined because the decision scenarios are unpredictable, the system itself must search the required…

Augmented marked graphs possess a special structure for modelling common resources as well as some desirable properties pertaining to liveness, boundedness, reversibility and conservativeness. This paper investigates the property-preserving composition of augmented marked graphs for the synthesis of distributed systems.…
