Research ArticleOpen accessIn the abstractExplicit Allocation Strategy with Deadline and Budget Constraint Algorithm in Bag of Tasks GridM. Suresh Kumar, T. PurusothamanProblem statement: This study is for effective scheduling of grid jobs based on economy for space shared resources in Bag of tasks grid. Grid Computing aims in combining the power of heterogeneous, geographically distributed, multi-domain computational resources to provide high performance or high throughput. Approach: Space shared resources are parallel supercomputers and clusters of workstations that provides a great amount … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 6,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractFPGA-Based Architecture for a Generalized Parallel 2-D MRI Filtering AlgorithmSami Hasan, Said Boussakta, Alex YakovlevProblem statement: Current Neuroimaging developments, in biological research and diagnostics, demand an edge-defined and noise-free MRI scans. Thus, this study presents a generalized parallel 2-D MRI filtering algorithm with their FPGA-based implementation in a single unified architecture. The parallel 2-D MRI filtering algorithms are Edge, Sobel X, Sobel Y, Sobel X-Y, Blur, Smooth, Sharpen, Gaussian and Beta (HYB). Then, the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 20 Feb 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Velocity Biased-Ad Hoc on Demand Distance Vector to Improve Throughput in Dynamic Mobile NetworkK. Tamizarasu, M. RajaramProblem statement: With the escalating demand for mobile ad hoc network projects, major challenges to system planners and designers were addressing stability and reliability problems due to frequent change of network topology. Controlling an overhead, which means bandwidth utilization due to control packets, depends on the routing protocol, topology and data traffic. Limiting the network control overheads, of this highly … …Journal of Computer Science, Vol. 8, Issue 2 · 21 Nov 2011 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Congestion Reduction Routing in Wireless Sensor NetworksT. V.P. Sundararajan, Thiyaneswaran Manoharan, Abinaya RajendranProblem statement: Data generated in wireless sensor networks may not all be alike: some data may be more important than others and hence may have different delivery requirements, To solve this problem addressed a differentiated data delivery in the presence of congestion in wireless sensor networks and proposed a class of algorithms that enforce differentiated routing based on the congested … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,799 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Modeling of IEEE 802.11e Enhanced Distributed Channel Access under a Non-Saturation ConditionG. Prakash, P. ThangarajProblem statement: The IEEE 802.11e EDCA protocol with different access Categories (ACs) supporting for Quality-of-Service (QoS). Due to internal or external packet collision, the Contention Window (CW) of the station increases the channel idle time under high Bit Error Rate (BER). Approach: In this study, we propose an analytical model for performance evaluation of IEEE 802.11e EDCA scheme under non-saturation … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Queue Management Scheme for Data CommunicationSheela Thavasi, Nityanandam NatarajanProblem statement: The growth in the needs of Internet applications that transmit massive amount of data has led to the emergence of Effective Queue Management. Approach: Queues were used to smooth spikes in incoming packet rates and to allow the router sufficient time for packet processing. When the waiting time is less a better queue management is ensured thereby resulting … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 7,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractNodes Density and Broadcast Management in Heterogeneous Environments of Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: The research presented in this study looks into Mobile Ad-Hoc Networks (MANETs) environment that has varying node densities, called heterogeneous density environment. Such environment can be roughly associated with situations varying from areas struck by disasters to normal city environments. Approach: This study improved the performance of existing MANETs routing protocols by reducing the communication overhead incurred during … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractThroughput-Delay Trade-Off for Slotted Aloha Multiple Access with Capture EffectA. Chehri, P. Fortier, P. M. TardifProblem statement: Medium Access Control (MAC) protocols are one of most important research issues in communication and networking. There have been proposed several MAC protocols in wireless as well in wired networks. Approach: ALOHA-based protocol is the simplest one, being able to provide prompt access, reliable channels and support for quality of service. However its limited capacity, low throughput and … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Nanostructured Stress Free Pt-Rich FePt Films for Micro Electro Mechanical System ApplicationsT. M. Selvakumari, R. N. Emerson, S. GanesanProblem statement: The electroplating technique is especially interesting due to its low cost, high throughput and high quality of deposit. Magnetic thin films are extensively used in various electronic devices including high density recording media and Micro Electro Mechanical (MEMS) devices.
