Research ArticleOpen accessIn the abstractReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Quantum and Classical Key Scheme for Two Servers Password AuthenticationA. Krishnan, T.S. ThangavelProblem statement: Traditional user authentication system uses passwords for their secured accessibility in a central server, which is prone to attack by adversaries. The adversaries gain access to the contents of the user in attack prone servers. To overcome this problem, the multi-server systems were being proposed in which the user communicate in parallel with several or all of the … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 6,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractCohesive Token Passing Algorithm Utilizing Software AgentsA. Fua’ad Abdulrazzak, Shamala SubramaniamProblem statement: The communications domain has utilized the implementation of protocols for a wide spectrum of applications. This encompasses Medium Access Control (MAC) protocols. MAC protocols have been extensively researched from several angles. This encompasses the implementation in the area of Wave Division Multiplexing (WDM) networks and Mobile Adhoc Networks (MANET). The relevance of intelligence in sustaining the pre-requisites for … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractQoS Based IPTV over LTE-WLAN Heterogeneous NetworksMohamed Matoui, Noureddine Moumkine, Abdellah AdibHeterogeneous networks required IP Multimedia Subsystem (IMS) technologies to perform their control signaling and improve their communication services. However, the highest IPTV-QoS cannot be performed using IMS only as it cannot differentiate between IPTV video components. In this paper, we implement our IPTV-flow label technique in LTE-WLAN heterogeneous systems that used to improve QoS by providing IPTV sub traffic priority … …Journal of Computer Science, Vol. 15, Issue 4 · 19 Apr 2019 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Conflict-Free Routing Tables Update Method for Persistent Multilink and Node Failures in SDN ArchitecturesYannick Florian Yankam, Jean Frédéric Myoupo, Vianney Kengne TchendjiThe large-scale network management abilities of centralized architectures, such as Software-Defined Networking (SDN), are attracting increasing interest from major computer networking companies. In this architecture type, the nodes follow the rerouting rules predefined by the control plane in the controller. However, when a link or node failure becomes persistent over the time, the controller must recompute the routing and rerouting … …Journal of Computer Science, Vol. 15, Issue 3 · 11 Mar 2019 · 7,469 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 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Scalable Hierarchal Based Addressing Routing Architecture in Software Defined Network (SDN)Ahmed Gaber Abu Abd-Allah, Ashraf Zaki Ghalwash, Aya Sedky AdlySoftware Defined Networking (SDN) designs are initiated with their own apprehensions and challenges that are needed to be addressed by researchers. A Controller, the main and the dominant network resource in SDN, has complex connections that lead to traffic overhead between other devices in the network and also from and to other Controllers. A Controller’s capacity of communications obtains will … …Journal of Computer Science, Vol. 16, Issue 8 · 3 Sep 2020 · 6,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cross-Layered Path Stability Based Routing Protocol for WiMAX NetworksM. Deva Priya, M. L. ValarmathiIn IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Cost Test Bench to Assess Energy Efficiency of Communications Network EquipmentLuiz Henrique Biazotto, Alexandre de Assis Mota, Lia Toledo Moreira MotaCommunication network Quality of Service (QoS) degradation can lead to the consumption of additional energy to exchange information than that needed in normal conditions. If such behavior is known, network management can be more efficient and accurate, permitting to control more efficiently the energy consumption in telecommunication equipments. This study describes a test bench that can simultaneously measure the QoS … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 6,678 accessesView PDFCite
