Research ArticleOpen accessIn the abstractCollaborative Caching Architecture for Continuous Query in Mobile DatabaseMohamed Ahmed Elfaki, Hamidah Ibrahim, Ali Mamat, Mohamed OthmanProblem statement: Cooperative caching, which allows sharing and coordination of cached data among clients, is a potential technique to improve the data access performance and availability in mobile ad hoc networks. However, variable data sizes, frequent data updates, limited client resources, insufficient wireless bandwidth and client’s mobility make cache management faces many challenges. Approach: In this study, we propose a … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 7 Jan 2011 · 8,875 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Design and Implementation of a Novel Skew Scenario Model in Mobile Ad Hoc NetworksN. Vetrivelan, A. V. ReddyProblem statement: In this research, it had been presented a novel Skew Scenario Model that has been developed and implemented for mobile ad hoc networks. There exist several mobility patterns that try to capture the behavior of the mobile devices under different circumstances, whereas in our work, the direction movement of the nodes is significantly specified horizontally, vertically and diagonally … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,922 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Survey of Compute Intensive Algorithms for Ribo Nucleic Acids Structural DetectionRa’ed Al-Khatib, Rosni Abdullah, Nur’Aini Abdul RashidProblem statement: Finding an accurate RNA structural alignment from primary sequence due to it is time consuming and computationally NP-hard problem is a major bioinformatics challenge. According to our investigation majority of current researches were concerned on achieving faster execution time, improving space complexity and better cache management. Recently one research introduced cache-efficient Chip Multiprocessor (CMP) algorithms with good speed-up … …Journal of Computer Science, Vol. 5, Issue 10 · 31 Oct 2009 · 6,458 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHydrophobic, Polar and Hydrogen Bonding Based Drug-Receptor Interaction of TetrahydroimidazobenzodiazepinonesV.K. Sahu, A.K.R. Khan, R.K. Singh, P.P. SinghAnti-HIV drug discovery has been increasingly focusing on HIV-1-RT (reverse transcriptase) as a potential therapeutic target. Tetrahydroimidazobenzodiazepinone (TIBO) belongs to non-nucleoside group of reverse transcriptase inhibitors (NNRTIs). A computational chemistry study has been performed on a series of tetrahydroimidazo-benzodiazepinones as HIV-1-NNRT inhibitors. Problem statement: In order to search out new drug of desired activity from the lead compounds, there was … …American Journal of Immunology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,837 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,314 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDFT Based Electrophilicity Index and QSAR study of Phenols as Anti Leukaemia AgentFarhan A. Pasha, Hemant K. Srivastava, Yakoob Beg, Pashupati P. singhDensity Functional reactivity indices based QSAR study of 49 phenol derivatives is presented in this paper. Two different models to describe the anti leukaemia activity of phenols have been made. First QSAR model includes molecular properties like molecular weight (Mw), hardness (η), chemical potential (μ), total energy, and electrophilicity index (ω). Various regression models have been made and regression quality … …American Journal of Immunology, Vol. 2, Issue 1 · 31 Mar 2006 · 7,587 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdaptive Reliable Efficient Multicasting Protocol for Mobile Ad Hoc NetworksK. Baskaran, A. Ebenezer Jeyakumar, V. Sumathy, J. Lakshmana PerumalThe Adaptive Reliable Multicast Protocol (ARM) with intermediate node support is introduced to guarantee message delivery to all multicast receivers in mobile ad hoc environment. ARM distributes multicast message cache and retransmission tasks among intermediate nodes to offer a scalable reliable multicasting. Due to limited memory and node’s mobility, ARM defines intermediate node as all nodes which overhear multicast messages. … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,818 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPERMUTATION OF HTTPI AND HTTPS IN WEB SERVICES AGAINST ATTACKS FOR SECURITY ENHANCEMENTS. Chakaravarthi, V. RamachandranThe Hyper Text Transfer Protocol (HTTP) protocol plays a vital role in Web Services Security. Though the HTTPs provide excellent security, they are not flexible enough to allow caches. HTTPi provides high integrity and low security whereas HTTPs provide low integrity and high security. The goal of WS activity is to build up set of technologies in order to direct … …Journal of Computer Science, Vol. 10, Issue 3 · 30 Nov 2013 · 6,884 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuery Based Client Indexing in Client/Server Information SystemsHagen HöpfnerOne issue in client/server information systems is the storage of the relationships between clients and data used by these clients. In particular in scenarios that allow the caching of data on the client site, this information can be used in order to keep the global database consistent. Thus, if the data on the server are updated, it is possible to … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,893 accessesView PDF Cite
