Research ArticleOpen accessIn the abstractGeneric Algorithm with Varying Block Sizes to Improve the Capacity of a Wireless Communications NetworksMahmoud AbdellaouiProblem statement: Channel capacity can be an essential parameter for wireless communication to improve the link quality. Until now, the channel capacity has been evaluated by utilizing Shannon capacity theory, but it presented many limitations and restrictions. The objectives of this study were to: (i) Expose, quantify, present and to give a clear and concise exposition of the mathematical principles … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractMPLS Based Architecture for Mobility and End-to-End QoS Support in Fourth Generation Mobile NetworksAlejandro Quintero, Eduardo Del FrutosProblem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractLoad Balancing on Open Networks: A Mobile Agent ApproachR. B. Patel, Neetu AggarwalIn order to disperse the load on a Web server, generally the server cluster is configured to distribute access requests, or mirror servers are distributed geographically on different networks. Use of the Internet and the World-Wide-Web (WWW) has become widespread in recent years and mobile agent technology has proliferated at an equally rapid rate to evenly distribute the requests to … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Interference Mitigation Techniques in 4G Networks in Mobile EnvironmentsEmna Hajlaoui, Abdelhakim Khlifi, Samia Dardouri et al.Intercell Interference (ICI) is one of the major factors that limit the performance and Quality of Service (QoS) of 4G wireless networks (Long Term Evolution/LTE-Advanced). For this reason, heterogeneous networks present an attractive solution for the improvement of mobile network’s services to provide better data rates and coverage. So, a key scheme in 4G traffic processing is the interference mitigation … …Journal of Computer Science, Vol. 15, Issue 12 · 25 Dec 2019 · 7,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Logic Decision Support System for Hypovigilance Detection based on CNN Feature Extractor and WN ClassifierInes Teyeb, Ahmed Snoun, Olfa Jemai, Mourad ZaiedFatigue and drowsiness are among the main causes of traffic accidents, just behind excessive speed and alcoholism. This paper deals with the problem of road safety. It attempts to present a driver vigilance monitoring system based on a video approach. This work aims at creating an assistive driving application employing eyes closure duration and head posture estimation as performant signs … …Journal of Computer Science, Vol. 14, Issue 11 · 22 Nov 2018 · 7,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractREVIEW CLUSTERING MECHANISMS OF DISTRIBUTED DENIAL OF SERVICE ATTACKSWesam Bhaya, Mehdi Ebady ManaaDistributed Denial of Service attacks (DDoS) overwhelm network resources with useless or harmful packets and prevent normal users from accessing these network resources. These attacks jeopardize the confidentiality, privacy and integrity of information on the internet. Since it is very difficult to set any predefined rules to correctly identify genuine network traffic, an anomaly-based Intrusion Detection System (IDS) for network … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Triple Play Services Using Multi Protocol Label Switching TechnologyWaheed Yasin, Hamidah IbrahimProblem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,524 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Botnet Detection System for P2P NetworksAtef Ahmed Obeidat, Majd Mahmoud Al-Kofahi, Mohammad Jazi Bawaneh, Essam Said HanandehBotnets remain an active security problem on the Internet and various computer networks. They are continuously developing with regard to protocols, structure and quality of attacks. Many botnet detection programs are currently available, but only few can detect bots in real-time. The sooner bots are detected the lesser damage they can cause. In this paper, a novel botnet detection system, … …Journal of Computer Science, Vol. 13, Issue 8 · 7 Aug 2017 · 7,414 accessesView PDFCite
