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…

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…

This paper presents the results of studies that made possible to propose a particular contribution to improve the quality on developing automotive embedded systems through a requirements specification template of a communication network based on CAN protocol. The whole template…

Statistical Bit Rate (SBR) transfer capability is considered a good option for supporting Variable Bit Rate (VBR) services. However, its study is somewhat in lag compared with Deterministic Bit Rate (DBR) or Available Bit Rate (ABR) capabilities. The definition of…

It has been observed that research in mobile agent focused on the development of platforms and on the application of the concept. Network awareness is one of the applications of mobile agent, concerning of how agent determine and make the…
