Research ArticleOpen accessIn the abstractImpact of MD5 Authentication on Routing Traffic for the Case of: EIGRP, RIPv2 and OSPFK. A. Al-Saud, H. M. Tahir, Moutaz Saleh et al.Problem Statement: With the free flow of routing data and the high availability of computer resources, possible threats to the networks can result in loss of privacy and in malicious use of information or resources that can eventually lead to large monetary losses. Approach: MD5 Authentication: Due to the major role that routing protocols play in computer network infrastructures, special … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Hierarchical Diff-EDF Schedulability over Heterogeneous Real-Time Packet NetworksMoutaz Saleh, Zulaiha Ali OthmanPacket networks are currently enabling the integration of traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to the best-effort traffic requiring no guarantees. QoS guarantees can be provided in conventional packet networks by the use of proper packet scheduling algorithms. As a computer revolution, many scheduling algorithms have been proposed to provide … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,530 accessesView PDFCite

Research ArticleOpen accessIn the abstractAdaptive Update Policy for Proactive Management of Deadline Miss Ratio and Data Freshness in Real-Time Database ModelsSanjay Tanwani, Ashwani K. RamaniImportant applications, like e-commerce, online stock trading, traffic control demand real-time data services. Conventional database perform poor at these applications. A database for real-time data services has to support timing constraints and temporal consistency in addition to supporting characteristics of a conventional database system. In other words, it is desirable to execute transactions within its deadline using updated data reflecting … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of a QoS-Aware Mechanism for Polling-Based High-Speed Network InterfacesSalman Al-Qahtani, Tarek Helmy, Khaled SalahThe explosive growth of the high-speed multimedia networks and the widespread use of web-based related applications place new demands on the network servers. The network end systems such as PC-Router, network server and host connected to high speed links must satisfy QoS requirements for multimedia traffics such as delay and loss ratio. Most works on operating systems support for high-speed … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Scheme for Improved Performance of Fixed Outage Rate Cellular SystemHussein M.Aziz Basi, M. B.R. MurthyThe traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA TIME SYNCHRONIZED HYBRID VEHICULAR AD HOC NETWORK OF ROADSIDE SENSORS AND VEHICLES FOR SAFE DRIVINGDahlia Sam, V. Cyril RajVANET is a type of ad hoc network in which the moving vehicles act as nodes. There has been lot of research for using VANETs in many applications. One of the main applications is the use of VANETs to improve driving safety. In any safety related applications, the vehicular nodes have to constantly communicate with each other and the roadside … …Journal of Computer Science, Vol. 10, Issue 9 · 10 Apr 2014 · 8,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticulate Matter in the Excavation Work Sites in Urban AreasGiuseppe Pizzo, Marina ClericoProblem statement: Excavation work sites in urban areas for infrastructures and buildings cause a great deal of disturbance and damage due to the emission of particulate matter, in particular in the area involved in urban renovation work. Under Italian legislation limits currently exist for PM10 and PM2, 5 but, in the case of excavation work sites, it would be also … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 23 Dec 2011 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetrieving Information from the Invisible Web Using Mobile AgentsFabien-Kenzo Sato, Samuel Pierre, Roch H. GlithoThis study proposes a model of information retrieval on the invisible Web by using the mobile agent paradigm. The developed architecture uses the power of a search engine to provide a list of sites of the invisible Web which are likely to be relevant and launches a dynamic search on these sites, thanks to mobile agents. To compare and experiment … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,839 accessesView PDFCite
