Research ArticleOpen accessIn the abstractA Routing Optimization Based on Cross-Layer Design for Wireless Multimedia Sensor Networks (WMSNs)Emansa Hasri Putra, Risanuri Hidayat, Widyawan, Wayan MustikaMultimedia applications are routed from source nodes via neighboring nodes to a sink in Wireless Multimedia Sensor Networks (WMSNs). However, the existing routing protocols in the WMSNs do not fulfill the quality of service (QoS) constraint yet for multimedia transmission. The WMSNs have specific characteristics such as multi-hop way, limited node capability and varying bandwidth, which can affect the quality … …Journal of Computer Science, Vol. 13, Issue 10 · 31 Oct 2017 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractIRED: An Improved Active Queue Management AlgorithmSamuel Oluwatosin Hassan, Adewole Usman Rufai, Samson Ojo Ogunlere et al.Quality of Service (QoS) of Internet routers is still challenged with the issue of congestion. Active Queue Management (AQM) algorithms aimed at improving end-to-end delay of packets by keeping the average queue size small. This objective is yet to be fully accomplished, especially for interactive services. In this study, an AQM algorithm named Improved Random Early Detection (IRED) algorithm based … …Journal of Computer Science, Vol. 18, Issue 3 · 28 Mar 2022 · 6,602 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Q-Routing Protocol Using Self-Aware Approach for Mobile Ad hoc NetworksAmal Alharbi, Abdullah Al-Dhalaan, Miznah Al-RodhaanMobile Ad hoc Networks (MANET) are self-organized networks that are characterized by dynamic topologies in time and space. This creates an instable environment, where classical routing approaches cannot achieve high performance. Thus, adaptive routing is necessary to handle the challenges in MANETs. Furthermore, it is necessary for nodes to be self-aware i.e., able to discover neighbors, links and paths when … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 7 Dec 2015 · 6,468 accessesView PDFCite

Parvatha VarthiniEvaluation of sharing on the Internet well- developed from energetic technique of grid computing. Dynamic Grid Computing is Resource sharing in large level high performance computing networks at worldwide. Existing systems have a Limited innovation for resource management process. In proposed work, Grid Computing is an Internet based computing for Optimal Resource Management Technique Operations (ORMTO). ORMTO are Elastic scheduling … …Journal of Computer Science, Vol. 9, Issue 8 · 9 Jul 2013 · 6,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultichannel Cognitive Cross Layer Optimization for Improved Video TransmissionMeenakshi Murugappan, Manimekalai Thirunavukkarasu, Maneesha S. MohanMultimedia applications particularly real-time video transmission in wireless networks, envisions end to end user perceived video quality as an important QoS parameter to be achieved. Cognitive Radio promising efficient spectrum utilization combined with Cross layer optimization is seen as a powerful combination to achieve the desired video quality. This study proposes Optimal Channel Sensed Multichannel Cognitive MAC (OCSM-CMAC), a QoS … …Journal of Computer Science, Vol. 9, Issue 1 · 6 Feb 2013 · 7,202 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 · 6,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnd to End Delay Improvement in Heterogeneous Multicast Network using Genetic OptimizationV. Chandrasekar, K. BaskaranProblem statement: Multicast is a concept of group communication which refers to transmitting the same data or messages from a source to multiple destinations in the network. This one-to-many group communication is a generalization of the concepts of one-to-one unicast and one-to-all broadcast. To deliver data from the sender to all receivers efficiently, routing plays an important role in multicast … …Journal of Computer Science, Vol. 8, Issue 9 · 13 Aug 2012 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdhoc on Demand Multipath Reliable and Energy Aware Quality of Service Routing for Mobile Adhoc NetworksV. Thilagavathe, K. DuraiswamyProblem statement: In a mobile adhoc network, there are a number of challenges for providing quality of service routing for multimedia applications and real time applications like voice transmission. The QoS parameters considered in this study are link reliability and energy consumption. Existing studies estimate the link reliability constraint between two nodes using exponentially distributed epoch lengths. The major problem … …Journal of Computer Science, Vol. 8, Issue 2 · 7 Nov 2011 · 7,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Selection of Multiple Resources Based on Virtual Private Network for Computational GridsG. Kavitha, V. SankaranarayananProblem statement: Grid computing provides a virtual framework for controlled sharing of resources across institutional boundaries. In computational grids, a client application is executed on the available set of resources that satisfy the user QoS requirements. Some applications require exhaustive computation power for execution of its tasks. In general, these tasks are assigned to a single available resource on the … …Journal of Computer Science, Vol. 7, Issue 12 · 22 Oct 2011 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Effective Contention Aware Stable Path Finding Approach to Provide Quality of Service in Mobile Ad hoc NetworksD. S. Thenmozhi, M. RajaramProblem statement: The application of Mobile Ad hoc NETworks (MANETs) has been increasing every day. Most applications that attract interest for use in current wired networks (e.g. video conferencing, on line movies and camera enabled instant messenger) would attract interest for MANETs also.
