Research ArticleOpen accessIn the abstractPerformance Analysis of Message Passing Interface Collective Communication on Intel Xeon Quad-Core Gigabit Ethernet and Infiniband ClustersRoswan Ismail, Nor Asilah Wati Abdul Hamid, Mohamed Othman, Rohaya LatipThe performance of MPI implementation operations still presents critical issues for high performance computing systems, particularly for more advanced processor technology. Consequently, this study concentrates on benchmarking MPI implementation on multi-core architecture by measuring the performance of Open MPI collective communication on Intel Xeon dual quad-core Gigabit Ethernet and InfiniBand clusters using SKaMPI. It focuses on well known collective communication … …Journal of Computer Science, Vol. 9, Issue 4 · 9 May 2013 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Cluster Based Routing Technique with Multiple Sinks for Wireless Sensor NetworksS. V. Manisekaran, R. VenkatesanProblem Statement: In order to reduce or minimize energy consumption and to improve bandwidth utilization in Wireless Sensor Networks (WSN), it was essential to consider its architecture in the network topology, power consumption, data rate and fault tolerance. Our objective is to formulate an effective cluster formation of nodes with multiple sinks to reduce power consumption and minimize the data … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards a Scalable File System on Computer Clusters Using DeclusteringVu Anh Nguyen, Samuel Pierre, Dougoukolo KonaréThis study addresses the scalability issues involving file systems as critical components of computer clusters, especially for commercial applications. Given that wide striping is an effective means of achieving scalability as it warrants good load balancing and allows node cooperation, we choose to implement a new data distribution scheme in order to achieve the scalability of computer clusters. We suggest … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Downward Handoff Latency in a WLAN/GPRS Interworking SystemMandalaparty B.R. Murthy, Fredson A. PhiriThis study presents the performance analysis of a new tight coupling based WLAN/GPRS interworking architecture. The effects of network traffic on downward handoff latency are investigated. The results indicate that increasing WLAN traffic increases the overall downward handoff latency more than increasing GPRS traffic. On the other hand, increasing GPRS traffic results in higher packet buffering requirements at the Serving … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF HIDDEN MARKOV MODEL BASED ADAPTIVE PROVISIONING OF OPTICAL BURST SWITCHING NETWORKS AMENABLE FOR UPGRADATION TO GREEN FLEXIGRID NETWORKSP. G.V. Ramesh, Prita NairCatering to the evolving bandwidth-on-demand applications requires flexible provisioning architectures that ensure fairness to both high end and low end users of internet. Dynamic classification of network paths into long and short, based on traffic dependent connection holding times and a wavelength allocation from different subsets for these categories is a necessity for implementing energy saving hybrid switching, loss recovery … …Journal of Computer Science, Vol. 10, Issue 5 · 16 Jan 2014 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECTIVE HEURISTIC ALGORITHM FOR DYNAMIC ROUTING AND BANDWIDTH MANAGEMENT UNDER QUALITY OF SERVICE CONSTRAINTS IN MULTISTAGE INTERCONNECTION NETWORKSR. Deepalakshmi, S. RajaramToday, Internet of Things (IoT) has introduced abundant bandwidth consumption and necessities in multimedia communications from online games to video-conferencing applications with the constraint of QoS requirements from time to time. The expected rapid proliferation of services would require performance unprecedented in the currently available best-effort routing algorithms. In, particular, the present routing mechanisms are based on the best-effort paradigm … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 7 Jan 2014 · 7,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Analysis of In-Band Crosstalk, Out-of-Band Crosstalk and GVD-Based Power Penalties in DWDM and TDM/DWDM-PONSIbrahim Mohamed, Mohammad Syuhaimi Ab-RahmanIn addition to the ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, the consequent upgrade from the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs) has become inevitable. Different architectures for creating a NG-OAN have been proposed in the literature. Among those architectures, … …Journal of Computer Science, Vol. 11, Issue 3 · 13 May 2015 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Middleware for Grid ComputingS. Muruganantham, P. K. Srivastha, KhanaaProblem statement: "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications and, in some cases, high-performance orientation. The role of middleware is to ease the task of designing, programming and managing distributed applications by providing a simple, consistent and integrated distributed programming environment. Essentially, middleware is … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,344 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Edge Efficient and Lightweight Hybrid CNN Vision Transformer Network With CBAM for IoT Based Plant Disease DetectionNyabeye Pangop Doris-Khöler, Kengni Ngangmo OlgaDetecting crop disease early enough to act on it remains a bottleneck for smallholder and precision farming alike, particularly when diagnosis depends on manual inspection or lab analysis that cannot keep pace with an outbreak. We present AgriViTNet, a compact CNN-Vision Transformer hybrid built for exactly this constraint: It extracts local texture cues through convolution, relates them across the whole … …Journal of Computer Science, Vol. 22, Issue 9 · 20 Sep 2026 · 586 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImplementing a Hybrid VMD–BiTCN–BiGRU Architecture With Intelligent Optimization for Agricultural Commodity Price Prognostication in Gujarat MarketsJignesh Hirapara, Ratnesh Kumar Namdeo, Ankit Kumar Dubey et al.In the agricultural sector, the prices of pulses require adequate forecasting to plan farming activities, store and market, and guide policy-making. However, the pulse price series is highly volatile, seasonal, nonstationary, and nonlinear, and thus conventional linear time series models are not necessarily very effective. In the suggested framework, the raw price data series is decomposed using Variational Mode Decomposition … …Journal of Computer Science, Vol. 22, Issue 7 · 1 Aug 2026 · 1,042 accessesView PDFCite
