Research ArticleOpen accessIn the abstractCIRCULAR NEIGHBOR REPLICATIONAhmad Shukri Mohd Noor, Nur Farhah Mat Zian, Yazid Md SamanDistributed system rely on replication techniques to tolerate data failure and site disconnection thus ensur-ing flexibility of the system so as to preserve its dependability. The idea of replication is robust however practical implementation of the replication techniques is often rigid that would bring down system's de-pendability and performance. This study intended to evaluate existing techniques and then develop a … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 8,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractMAPREDUCE CHALLENGES ON PERVASIVE GRIDSL. A. Steffenel, O. Flauzac, A. S. Charao et al.This study presents the advances on designing and implementing scalable techniques to support the development and execution of MapReduce application in pervasive distributed computing infrastructures, in the context of the PER-MARE project.

Research ArticleOpen accessIn the abstractREVIEW CLUSTERING MECHANISMS OF DISTRIBUTED DENIAL OF SERVICE ATTACKSWesam Bhaya, Mehdi Ebady ManaaDistributed Denial of Service attacks (DDoS) overwhelm network resources with useless or harmful packets and prevent normal users from accessing these network resources. These attacks jeopardize the confidentiality, privacy and integrity of information on the internet. Since it is very difficult to set any predefined rules to correctly identify genuine network traffic, an anomaly-based Intrusion Detection System (IDS) for network … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractA MULTI ATTRIBUTE RANKING MECHANISM FOR PEER-TO-PEER NETWORKSSheila Anand, B. SwaminathanP2P systems are envisioned to play a greater role in collaborative applications. P2P environments remove the challenging task of using servers for information sharing. Emerging collaborative P2P systems require discovery and utilization of multi-attribute, distributed and dynamic group of resources to achieve greater tasks beyond conventional file and processor cycle sharing. The process of selection of a peer for collaborative … …Journal of Computer Science, Vol. 10, Issue 8 · 24 Feb 2014 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING FAULT TOLERANT RESOURCE OPTIMIZED AWARE JOB SCHEDULING FOR GRID COMPUTINGK. Nirmala Devi, A. TamilarasiWorkflow brokers of existing Grid Scheduling Systems are lack of cooperation mechanism which causes inefficient schedules of application distributed resources and it also worsens the utilization of various resources including network bandwidth and computational cycles. Furthermore considering the literature, all of these existing brokering systems primarily evolved around models of centralized hierarchical or client/server. In such models, vital responsibility such … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeb-Enabled Generalized Architectural Model for Online Power System AnalysisBoopathi C. Sengodan, Subhransu Sekhar Dash, Subramani Chinnamuthu et al.In this study, an effective Web-enabled generalized architectural model is proposed. The proposed model makes the power system analysis to be completely secured, distributed, platform-independent and language-independent. Although significant progress has been made for on-line power system analysis in distributed environment, still efficient distributed environment has not yet been exploited. The Web-enabled architectural models are emerging as basic methodologies to … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,717 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Fault Tolerant Scheduling Approach for Computational GridP. Keerthika, N. KasthuriGrid computing serves as an important technology to facilitate distributed computation computational grids solve large scale scientific problems using heterogeneous geographically distributed resources. Problems like dispatching and scheduling of tasks are considered as major issues in computational grid environment. The Grid Scheduler must select proper resources for executing the tasks with less response time.
