Research ArticleOpen accessIn the abstractA CROSS-LAYER SCHEDULER WITH CHANNEL STATE INFORMATION FOR GUARANTEED QUALITY OF SERVICER. Nandhini, N. DevarajanWiMAX networks are deployed for commercial use because of its nature high bandwidth. This requirement invokes the application level changes in QoS provisioning techniques. The objective of the broadband wireless technologies is to ensure the end to end Quality of Service (QoS) for the service classes. WiMAX is a revolution in wireless networks, which could support real time multimedia services. … …Journal of Computer Science, Vol. 10, Issue 2 · 13 Nov 2013 · 6,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Discrete Wavelet Transform Based Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing System for Different Wavelets in Different Channel EnvironmentHariprasadNagarajan, AlameluNachiappanMultiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are the two assuring technologies that offers high data rate as required for the 4G wireless systems. Conventionally OFDM is Fast Fourier Transform (FFT) based system. It uses IFFT (Inverse FFT) blocks in the transmitter and FFT blocks in the receiver. OFDM combined with MIMO gives increased throughput and … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 18 Oct 2013 · 6,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Newton Raphson Algorithm for Optimizing Transmission Control Protocol PerformanceJ. Viji Priya, S. SuppiahWireless networks are growing rapidly. TCP is the most widely-used protocol on Internet and so optimizing TCP performance is very important for fast efficient data transfer. The different existing TCP variants and solutions they have not been analyzed together to identify the bottlenecks in wireless networks. TCP has a major problem in its congestion control algorithm which does not allow … …Journal of Computer Science, Vol. 9, Issue 5 · 20 May 2013 · 6,306 accessesView PDFCite
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 abstractA Hybrid Approach for Node Co-Operation Based Clustering in Mobile Ad Hoc NetworksC. Sathiyakumar, K. DuraiswamyA Mobile Ad-Hoc Network (MANET) is termed as a set of wireless nodes which could be built with infrastructure less environment where network services are afforded by the nodes themselves. In such a situation, if a node refuses to co-operate with other nodes, then it will lead to a considerable diminution in throughput and the network operation decreases to low … …Journal of Computer Science, Vol. 9, Issue 2 · 26 Mar 2013 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fault Tolerant Resource Allocation Architecture for Mobile GridS. Thenmozhi, A. Tamilarasi, P. T. VanathiProblem statement: In order to achieve high level of reliability and availability, the grid infrastructure should be fault tolerant. Since the failure of resources affects job execution fatally, fault tolerance service is essential to satisfy QoS requirement in grid computing with respect to mobile nodes. Approach: We propose a fault tolerant technique for improving reliability in mobile grid environment considering … …Journal of Computer Science, Vol. 8, Issue 6 · 7 Apr 2012 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multipath Energy Efficient Congestion Control Scheme for Wireless Sensor NetworkB. Chellaprabha, S. Chenthur PandianProblem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with … …Journal of Computer Science, Vol. 8, Issue 6 · 20 Mar 2012 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensity Based Routing Algorithm for Spare/Dense Topologies in Wireless Mobile Ad-Hoc NetworksEssam Natsheh, Khalid BuraggaProblem statement: A Mobile Ad-Hoc Networks (MANETs) operate in environments without infrastructures with an undefined network size. Most routing protocols of Mobile Ad-hoc Networks (MANETs) were studied using open space models where nodes were able to move throughput the entire simulation area. However, a more realistic topology should account for restricted mobility of nodes, such as in an urban city … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,465 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Widely Used Diagnostics "DNA Microarray"-A ReviewR. Manoj KumarProblem statement: DNA microarray technique is one of the latest advances in the field of molecular biology and medicine. It is a multiplex technique used in combination of bioinformatics and statistical data analysis. Since, 1995, the technique offers the possibility of conducting tens or hundreds of thousands of simultaneous hybridizations. Approach: This increased experimental efficiency permits high throughput and whole … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractMitochondrial Energy-Deficient Endophenotype in AutismJ. Jay Gargus, Faiqa ImtiazWhile evidence points to a multigenic etiology of most autism, the pathophysiology of the disorder has yet to be defined and the underlying genes and biochemical pathways they subserve remain unknown. Autism is considered to be influenced by a combination of various genetic, environmental and immunological factors; more recently, evidence has suggested that increased vulnerability to oxidative stress may be … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 11,518 accessesView PDFCite
