Research ArticleOpen accessIn the abstractPerformance Evaluation of Handover in WiMax with TCP and UDP as Underlying ProtocolKaram Dhafer Mayoof, Rosilah Hassan, Amjed Sid Ahmed, Ahmed MarwanThe rejection of an ongoing connection/session is serious problem and it degrades the QoS and efficiency of the network rather than rejecting a request for new connection. The impact on performance of handovers is a serious problem in cellular systems that must be addressed. During handover there may be delay in packets and connections may drop. Real time applications i.e., … …Journal of Computer Science, Vol. 11, Issue 9 · 12 Dec 2015 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Combined Call Admission Control and Scheduling Algorithm to Improve Quality of Service for Multimedia Services Over Next Generation Wireless NetworksG. Nantha Kumar, A. ArokiasamyWe nominate a weighted service queuing approach, each service queue is allotted a preset priority weight and Call Admission Control scheme for service classes defined in IEEE 802.16 standard. Different group of queues have been implemented to transmit different service classes. Allocation of bandwidth usage of each service classes are relying on maximum data that could take part in connection … …Journal of Computer Science, Vol. 11, Issue 2 · 20 Sep 2014 · 6,482 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 · 6,517 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Multipath Routing and Wavelength Allocation Using Traffic Grooming in Optical Wavelength Division Multiplexing Mesh NetworksV. Rajamani, T. KavithaIn optical WDM mesh networks, traffic grooming is essential in order to utilize the bandwidth efficiently to minimize the cost and meet the user service requirement. By grooming traffic, it is possible to reduce the total cost of all Add drop multiplexer needed. Also for the high processing capability in a WDM network, the path should be capable of carrying … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutrient and the Mind-Body Axis, in Relation to Omega-3 Fatty Acids and Amino AcidsToru Takahashi, Eri Toda, Ram B. Singh et al.Noncommunicable Diseases (NCDs); obesity, type 2 diabetes mellitus, Cardiovascular Diseases (CVDs) and cancer have become major health problems in both developing and developed countries. Physical inactivity and increased intake of energy rich proinflammatory foods in association with genetic predisposition are common primary risk factors for these problems. Mind-body interactions and mechanisms in relation to hypothalamus neurotransmitters and vagus nerve have … …Current Research in Medicine, Vol. 3, Issue 1 · 17 Feb 2012 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Programmable Gate Arrays based Design, Implementation and Delay Study of Braun's MultipliersMuhammad H. Rais, Mohammed H. Al MijalliProblem statement: Parallel array multipliers are required to achieve high execution speed for Digital Signal Processing (DSP) applications. Approach: The purpose of this article is to investigate Field Programmable Gate Arrays (FPGAs) implementation of standard Braun’s multipliers on Spartan-3AN, Virtex-2, Virtex-4 and Virtex-5 FPGAs using Very high speed integrated circuit Hardware Description Language (VHDL). The delay study was analyzed using … …Journal of Computer Science, Vol. 7, Issue 12 · 22 Oct 2011 · 6,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Position System Implementation over Vehicular Ad Hoc Networks in 2-Dimension SpaceSoumen Kanrar, Mohammad SirajProblem statement: The real world scenario have changed from the wired connection to wireless connection. Over the years software development has responded to the increasing growth of wireless connectivity in developing network enabled software. The problem arises in the wireless domain due to random packet loss in transport layer and as well as in data link layer for the end … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Platform to Develop a Secure Instant Messaging Using Jabber ProtocolGhossoon M.W. Al-SaadoonProblem statement: Open Source technologies are interesting in that they allow free experimentation and integration by anyone and anywhere. A Jabber user can control presence with very little effort. Another user, regardless of external platform, must subscribe to your presence.

Research ArticleOpen accessIn the abstractThe Land Uses' Consequences in Coastal Area of Faliraki and Delta Penaeus River in GreeceAgisilaos EconomouProblem statement: The areas of Faliraki and Delta Pinaeus river is presented with downgrade in natural resources that has a direct affect on the future development of these areas. This research investigated (i) whether land uses have downgraded the coastal areas (ii) to which degree the determination of land uses can play an important role in the reduction of environmental … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 7,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Meaning of a Redundant Codon: There is Protein Folding Information in Nucleic Acids in Addition to the Genetic CodeJan C. Biro, Josephine M.K. BiroAll the information necessary for protein folding is supposed to be present in the amino acid sequence. It is still not possible to provide specific ab initio structure predictions by bioinformatical methods. It is suspected that additional folding information is present in protein coding nucleic acid sequences, which is not represented by the known genetic code. Nucleic acid subsequences comprising … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 8,292 accessesView PDFCite
