Research ArticleOpen accessEvery word in the titleInternational Economic Relations and Information Communication Technologies (ICT) Use: Economic Globalization via Economic DigitalizationAthanasios I. BozinisThe definition of globalization refers to the unification of the countries international economies, as an even system distinctive for its intense mutual reliant association. Globalization does not demand natural presence of the countries in order to conduct product exportation or importation, since all economical procedures may be achieved through the propagation of information and financial capitals. The scope of this … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,320 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCommunication Architecture Synthesis for Multi-bus SoCAbdelkrim Zitouni, Sami Badrouchi, Rached TourkiIn the systems on chip (SoC) design, the synthesis of communication architecture constitutes the bottleneck which can affect the performances of the system. Various schemes and protocols can be necessary, just as various topologies of interconnection. To reduce the complexity of the communications refinement, we present in this study a model and a synthesis approach for multi-bus communication architecture containing … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,784 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntensity Position Modulation for Free-Space Laser Communication SystemF. Faghihi, A. JangjooIn this study a novel analog modulation-demodulation technique for free-space laser communication system called Intensity Position Modulation (IPM) is carried out. According to TEM00 mode of a laser beam and by linear fitting on the Gaussian function as an approximation, the variation of the linear part on the reverse biased pn photodiode produced various currents. Our simulated results show fine … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,603 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHardware Design of Wireless Physical Token Ring System for Mobile and Cell CommunicationNidal F. Shilbayeh, Mahmoud Z. IskandaraniA wireless network system based on an infrared and Laser scanning Physical Token Ring architecture (W-PTRS) was designed, built and tested successfully. The network provides a different way of utilizing the concept of a token ring network but with a higher efficiency related to the speed of data transfer and the ability to parallel process client-server requests leading to a … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,792 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePath Loss Measurements for Wireless Communication in Urban and Rural EnvironmentsYahia Zakaria, Jiri Hosek, Jiri MisurecPath loss models are useful planning tools that allow the designers of wireless communication networks to achieve optimal levels for the base station deployment and meeting the expected service level requirements. In this study various propagation models (COST 231 Walfisch-Ikegami W-I, Ericsson and Stanford University Interim SUI) are analyzed and compared with the measurements. The measured data were taken in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 16 Apr 2015 · 7,837 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOPTIMIZING BATCH REKEYING INTERVAL FOR SECURE GROUP COMMUNICATION BASED ON QUEUING MODELA. Vasanthi, T. PurusothamanRapid growth of Internet spawns many group oriented multicast applications like Internet pay TV, news dissemination and stock quote system. The fortes of these applications are the support of dynamic, scalable group membership and group members are geographically divergent. As members of the group move in and out, an imperative cryptographic rekeying model should be applied to preserve the confidentiality … …Journal of Computer Science, Vol. 10, Issue 2 · 20 Nov 2013 · 6,460 accessesView PDFCite
