Facing the different approaches to process activation and global termination detection on distributed systems, this paper performs a practical comparison between the mainly opposed centralized and distributed models. Firstly, they were implemented to solve both the activation and termination detection…

System survivability is the ability to give service in spite
of failures of some of the components. To assure survivability is an important goal when designing a communications network backbone, to ensure that it can resist to failures in the…

Evolving neural arrays (ENA) have proved to be capable of learning complex behaviors, i.e., problems whose solution requires strategy learning. For this reason, they present many applications in various areas such as robotics and process control. Unlike conventional methods "based…

In Bluetooth networks, devices are organized into small piconets and large scatternets, and each node acts as the role of master, slave or gateway. Due to dynamic topology changes, different bandwidth available and unpredictable interference of media in Bluetooth networks,…

Many classification systems rely on clustering techniques in which a collection of training examples is provided as an
input, and a number of clusters c<SUB>1</SUB>,...c<SUB>m</SUB> modelling some concept C results as an output, such that every cluster c<SUB>i</SUB> is labelled…

In order to accomplish collaborative product development in the area of engineering, a work platform is needed to support all-sided collaborative work by the different development partners at geographically different locations. The platform is established on the basis of a…

Processor and network management have a great impact on the performance of Distributed Memory Parallel Computers. Dynamic Process Migration allows load balancing and communication balancing at execution time. Managing the communications involving the migrating process is one of the problems…

This article presents a proposal of a multithreaded core for an OSI/ISO management agents including its modeling,
simulation and performance evaluation. The proposed model i s compared against another one (unthreaded core) which is the c ommonly adopted model by…

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,…

A large quantity of data of different types and priorities pass through on high-speed networks. A relevant part of these data, like continuous media (audio, video, and so), need a control of its Quality of Service (QoS). This paper describes…
