Research ArticleOpen accessIn the abstractA Secure Chat Application Based on Pure Peer-to-Peer ArchitectureMohamad Afendee Mohamed, Abdullah Muhammed, Mustafa ManChat application is increasingly used as an alternative to older communication technologies such as telephony and telegraph. Equipped with advanced features, people can use it for education, business and socialize. Basic requirement for chatting is an ability to exchange text messages, however, recent releases include support for audio and video communications. For some reasons, peer-to-peer now turned out to be … …Journal of Computer Science, Vol. 11, Issue 5 · 26 Jun 2015 · 7,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrum Switchover for Commercial use and "Spectrum Procurement" ContestAlexander RymanovMotivated by the need to implement wireless broadband mobile communications (Long Term Evolution (LTE)) in the "Digital Dividend" band (790-862 MHz) in Russia and to relocate government users of spectrum, especially the Aeronautical Radio Navigation Service (ARNS), this article focuses on the funding of organizational and technical measures to relocate government users from the spectrum and to transfer the spectrum … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 10 Dec 2014 · 6,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOBILE COMMUNICATIONS FOR USING IN TELEMEDICINEMarjan Ghazi Saeedi, Mashaallah Torabi, Sakineh Hamidi, Hassan RanjiTelemedicine the use of telecommunication and information technologies in order to provide clinical health care at a distance helps eliminate distance barriers and can improve access to medical services that would often not be consistently available in distant rural communities. It is also used to save lives in critical care and emergency situations. Although there were distant precursors to telemedicine, … …Current Research in Medicine, Vol. 5, Issue 1 · 12 Feb 2014 · 9,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractREDUCING TRANSMITTED POWER OF MOVING RELAY NODE IN LONG-TERM EVOLUTION-ADVANCED CELLULAR NETWORKSJaafar A. Aldhaibani, A. Yahya, R. B. Ahmad et al.Wireless multi-hop relay networks have become very significant technologies in mobile communications. These networks ensure data rate transfer and coverage extension with a low cost. In this study two types of relay are studied; Fixed Relay Node (FRN) and Moving Relay Node (MRN). Where system analyses for uplink and downlink transmission are derived in this study. Moreover the optimal relay … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgent and Radio Frequency Identification Based Architecture for Supermarket Information SystemHasan Al-SakranIn recent years the acceptance of Radio Frequency Identification (RFID) technology in business environments has been increasing rapidly due to its competitive business value. Adopting a suitable RFID-based information system has become increasingly important for supermarkets. However, most supermarkets still use conventional barcode-based systems to manage their information processes, which are consistently reported as one of the most unenthusiastic aspects … …Journal of Computer Science, Vol. 9, Issue 6 · 1 Jun 2013 · 6,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Security Model using Multilayer Approach for E-Health ServicesRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: Delivering services online is important in e-health. Services that are delivered through online communications between engaging parties, often involve sensitive information transmitted over the Internet. However, while the Internet successfully facilitates these services, significant threats also come in parallel. Network attacks, information breaches and malicious software on a computer system are common threats to the Internet. These threats … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 6,822 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital Hardware Implementation of a Neural System Used for Nonlinear Adaptive PredictionHassène Faiedh, Chokri Souani, Kholdoun Torki, Kamel BesbesNeural networks have been widely used for many applications in digital communications. They are able to give solutions to complex problems due to their nonlinear processing and their learning and generalization. Neural networks are one of the key technologies for the communication domain and accordingly a special effort may be expected to be paid to real time hardware implementation issues. … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,763 accessesView PDFCite
