Research ArticleOpen accessEvery word in the titleGeometrical Approach to a New Hybrid Grid-Based Gravitational Clustering AlgorithmFaisal Bin Al Abid, A.N.M. Rezaul Karim, Golam Rahman ChowdhuryIn the past years, several clustering algorithms have been developed, for example, K-means, K-medoid. Most of these algorithms have the common problem of selecting the appropriate number of clusters and these algorithms are sensitive to noisy data and would cause less accurate clustering of the data set. Therefore, this paper introduces a new Hybrid Grid-based Gravitational Clustering Algorithm (HGGCA) geometrically, … …Journal of Computer Science, Vol. 17, Issue 3 · 9 Mar 2021 · 6,783 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleScheduling Jobs through Gap Filling and Optimization Techniques in Computational GridOmar Dakkak, Shahrudin Awang Nor, Suki ArifDue to the heterogeneity and complexity in grid computing, classical algorithms may not be able to deal with dynamic jobs properly. In the dynamic mode, incoming jobs reach the scheduler arbitrary. Therefore, scheduling the jobs using simple policy alone deteriorates the performance of the scheduler. Thus, a policy that can handle the dynamicity efficiently is indispensable. This paper presents the … …Journal of Computer Science, Vol. 13, Issue 5 · 17 May 2017 · 7,418 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGIS-Based Optimal Site Selection for Installation of Large-Scale Smart Grid-Connected Photovoltaic (PV) Power Plants in Selangor, MalaysiaSabo Mahmoud Lurwan, Mohammed Oludare Idrees, Goma Bedawi Ahmed et al.This study presents a GIS-based model to identify optimal sites to install large-scale smart grid-connected Photovoltaic (PV) power plants. Input datasets include digital elevation model, road networks, grid lines and daily average solar radiation. Using multi-criteria decision-making approach, we set constraining conditions for slope, proximity to the road, proximity to grid lines, solar radiation and land use to optimize the … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Jan 2017 · 8,783 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Secure Unicast/Multicast Authentication and Key Distribution Protocols for Smart GridSamah Mohamed Sayed, Heba Kamal Aslan, Ayman Mohamed HassanThis study discusses the problem of key distribution protocol in IoT systems especially smart grids for two modes of communication: Unicast and multicast. In the present paper, we suggested two protocols for key distribution for both unicast and multicast communication. The proposed schemes are based on symmetric key encryption with cryptographic primitives: Hashes and nonces. In addition, the multicast key … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 4 Jan 2023 · 5,424 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Improved Positivity Preserving Odd Degree-N Said-Ball Boundary Curves on Rectangular Grid Using Partial Differential EquationAhmed Kherd, Azizan Saaban, Noraziah Haji ManThis paper discusses the sufficient conditions for positivity preserving odd degree-n Said-Ball boundary curves defined on a rectangular grid. We derive a sufficient condition on boundary curves of rectangular Said-Ball patches where the lower bound ordinates are adjusted independently. To construct the boundary curves for each rectangular patch, the Said-Ball polynomial solution of fourth order PDE will be considered where … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 10 Apr 2016 · 6,740 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA CLUSTERING-BASED HYBRID REPLICA CONTROL PROTOCOL FOR HIGH AVAILABILITY IN GRID ENVIRONMENTRohaya Latip, Zulaile Mabni, Hamidah Ibrahim et al.In recent years, with the emergence of grid computing system, the number of distributed sites has become very large. When thousands of sites involved in a grid computing system, data replication can improve data availability, communication cost and provide fault-tolerance in the system. In the literature, many replica control protocols have been proposed for managing replicated data. However, in large … …Journal of Computer Science, Vol. 10, Issue 12 · 24 Dec 2014 · 8,487 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQUANTITATIVE EVALUATION OF JOB AND RESOURCES FOR BETTER SELECTION TO IMPROVE MAKESPAN IN GRID SCHEDULINGKrishnamoorthy Natarajan, Asokan Ramasamy, Sangeetha SubramanianThis study presents the Priority based ranking of jobs and resources to improve the Makespan in the grid scheduling problem. Grid environment’s effectiveness largely depends on scheduler’s effectiveness/efficiency as they act as local resource brokers. The scheduler is responsible to select resources/scheduling jobs so that users/application requirements are met regarding overall execution time (throughput) and the resources use cost. The … …Journal of Computer Science, Vol. 10, Issue 5 · 4 Jan 2014 · 6,554 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResource Selection in Grid Environment Based on Trust Evaluation Using Feedback and PerformancePrakash Mohan, Ravichandran ThangavelA grid computing is a collection of distributed computing resources owned by many organizations across boundaries and not dedicated for a single user available in the Virtual Organization. Grid computing environment provides more computational capabilities to increase the scalability and efficiency of the infra-structure. Resource selection in computational grid is the open issue for executing complex jobs. Trust is the … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,169 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Fuzzy Based Mechanism For Allocation of Grid ResourcesM. Poonguzhali, S. ShanmugavelOne of the main challenges in Grid computing is efficient allocation of resources (CPU-hours, network bandwidth) to the tasks submitted by users. In our previous work a technique to allocate resources in a grid environment using predicted data has been proposed. We propose utilization of the predicted data the resources were classified into three types; they are permanent resources, semi-permanent … …Journal of Computer Science, Vol. 9, Issue 5 · 23 May 2013 · 6,772 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGrid Voltage Stability Enhancement Using Photovoltaic Based Static Synchronous CompensatorSubhransu Sekhar Dash, Arun Bhaskar Mayilvaganan, Venkatesh VenkataramananToday, we are mostly dependent on non renewable energy that have been and will continue to be a major cause of pollution and other environmental degradation. Because of these problems and our dwindling supply of petroleum, finding sustainable alternatives is becoming increasingly urgent. Perhaps, the greatest challenge is in devising a sustainable future, which relies on integration and control of … …Journal of Computer Science, Vol. 9, Issue 3 · 17 Apr 2013 · 6,861 accessesView PDFCite
