Research ArticleOpen accessEvery word in the titleSolving Two Deadlock Cycles through Neighbor Replication on Grid Deadlock Detection ModelNoriyani Mohd Zin, A. Noraziah, Ahmed N. Abdalla, Ainul Azila CheFauziA data grid is compose of hundreds of geographically distributed computers and storage resources usually locate under different places and enables users to share data and other resources. Problem statement: Data replication is one of the mechanisms in managing data grid architecture that receive particular attention since it can provide efficient access to data, fault tolerance, reduce access latency and … …Journal of Computer Science, Vol. 8, Issue 2 · 1 Dec 2011 · 7,257 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titlePerformance Improvement and Deadlock Prevention for a Distributed Fault Diagnosis AlgorithmThabit S. MohammedThis research presents an overview to the issue of fault diagnosis in distributed systems and an evaluation study to some of the algorithms proposed in literature for performing distributed fault diagnosis. One algorithm was chosen and adopted for implementation in a simulator for investigation. A strategy for improving the performance of this algorithm and preventing deadlock was proposed in this … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 6,908 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDistributed Mutual Exclusion Based on Causal OrderingMohamed Naimi, Ousmane ThiareProblem statement: Causality among events, more formally the causal ordering relation, is a powerful tool for analyzing and drawing inferences about distributed systems. The knowledge of the causal ordering relation between processes helps designers and the system itself solve a variety of problems in distributed systems. In distributed algorithms design, such knowledge helped ensure fairness and liveness in distributed algorithms, … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 6,748 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign, Validation, Simulation and Parametric Evaluation of a Novel Protocol for Locating Mobile Agents in Multiregion EnvironmentRama Sushil, Kumkum Garg, Rama BhargavaMobile agents are processes that can be dispatched from source computer and be transported to remote servers for execution, have been widely argued to be an important enabling technology for future systems. Location management is a necessity for locating mobile agents in a network of mobile agent hosts for controlling, monitoring and communication during processing and it still represents an … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 6,936 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTowards an Exclusion Mutual Tolerant Algorithm to FailuresM. Senouci, A. Liazid, D. BenhamamouchThe distributed algorithmic is widely used in various economic and industrial fields as finance, medical, industry, telecommunication. New technologies are increasing rapidly. From now on, applications must associate two conditions: auto-execution on heterogeneous grid computers, on the one hand and on the other hand, satisfaction of the temporal and safety constraints. Hence this paper deals with performing an algorithm based … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,726 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReal-time Optimistic Concurrency Control based on Transaction Finish DegreeHan Qilong, Hao ZhongxiaoConcurrency control is one of the main issues in the studies of real-time database systems. Optimistic concurrency control algorithms have the attractive properties of being non-blocking and deadlock-free. However, they have the problems of late conflict detection and transaction restarts. Although the number of transaction restarts is reduced by dynamic adjustment of serialization order in real-time database systems, they are … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,688 accessesView PDF Cite
