Research ArticleOpen accessPhrase in the titleA Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc NetworksR. Asokan, A. M. Natarajan, A. NivethaQuality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRK4 Differential Equation to improve QoS in an eUTRAN LTE Network: A Deterministic vs. Stochastic ApproachBrou Pacôme, Pandry Ghislain, Bodjré Aka Hugues Félix, Oumtanaga SouleymaneImproving Quality of Service (QoS) in an eUTRAN LTE network is essential to guarantee optimal performance in the face of dynamic variations in user traffic and radio channel interference. In this context, this paper explores the use of 4th-order Runge-Kutta differential equations (RK4) to model and optimize radio resource management, by comparing a deterministic approach, which assumes stable and predictable … …Journal of Mathematics and Statistics, Vol. 21, Issue 1 · 3 Jul 2025 · 5,877 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFeasibility of Desktop Virtualization Per Software Services and Local Hardware Based on the Network ThroughputVitor Chaves De Oliveira, Inacio Henrique Yano, Alexandre De Assis Mota, Lia Toledo Moreira MotaIn recent years, virtualization computing has become a worldwide reality present in datacenters servers of most organizations. The motivations for the use of this solution are focused primarily on cost reduction and increases in availability, integrity and security of data. Based on these benefits, recently it was started the use of this technology for personal computers as well. That is, … …Journal of Computer Science, Vol. 9, Issue 7 · 15 Jun 2013 · 6,725 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpacts of Application Usage and Local Hardware on the Throughput of Computer Networks with Desktop VirtualizationVitor Chaves De Oliveira, Alexandre De Assis Mota, Lia Toledo Moreira MotaCurrently, virtualization solutions are employed in the vast majority of organizations around the world. The reasons for this are the benefits gained by the approach, focusing on increases in security, availability and data integrity. These privileges are also present in a new technique, which emerges from this same concept and is called desktop virtualization. This method, compelled by these advantages, … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 28 Jan 2013 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUtility Based Scheduling and Call Admission Control for Long Term Evolution NetworksJ. Vijay Franklin, K. ParamasivamIn this study, we propose to design a call admission control algorithm which schedules the channels for Real time and non-real time users. In Long Term Evolution (LTE) 3GPP Networks, several works were done on call admission control but these works rarely considers scheduling of resources to the real time and non-real time users.When the system meets traffic oriented performance … …Journal of Computer Science, Vol. 8, Issue 12 · 13 Dec 2012 · 6,785 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFuzzy Based Dynamic Buffer Management in Wimax 16m NetworksD. Karunkuzhali, Dinesh Chandra TomarIn WiMAX 16m networks, buffer allocation is the major problem to be handled for offering Quality of Service (QoS). The lack of buffers increases the packet loss and queuing delay. In this study we propose a fuzzy based dynamic buffer management in WiMAX 16 m network. The Base Station (BS) estimates the parameters such as number of user requests, flow … …Journal of Computer Science, Vol. 8, Issue 12 · 8 Nov 2012 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Fuzzy Logic Based Power Control for Wideband Code Division Multiple Access Wireless NetworksN. Mohan, T. RavichandranProblem statement: Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required Quality of Service (QoS) parameters. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Efficient CAC is necessary for the QoS provisioning in … …Journal of Computer Science, Vol. 8, Issue 8 · 4 Aug 2012 · 6,755 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Cross Layer Frame Work for Enhanced Quality of Service Provisioning in Worldwide Interoperability for Microwave Access NetworksS.J.K. Jagadeesh Kumar, T. PurusothamanProblem statement: The demand for multimedia applications in WiMAX networks is growing at a rapid pace. A method for guaranteeing Quality of Service (QoS) for different classes of traffic is therefore gaining importance. Hence designing and analyzing multimedia traffic and QoS parameters has become central to this problem. In this study, we propose a cross layer frame work in which … …Journal of Computer Science, Vol. 8, Issue 3 · 21 Jan 2012 · 7,052 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHybrid Traffic Management Model for Multi-Protocol Label Switching NetworkE. R. Naganathan, S. RajagopalanProblem statement: MPLS is a highly scalable, protocol agnostic and data-carrying mechanism. Traffic engineering is the major research area in MPLS due to the emerging requirements of MPLS and the internet usage. A major objective of traffic engineering is to minimize or eliminate high-loss situations. Another goal of traffic engineering is to balance the Quality of Service (QoS) against the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,094 accessesView PDFCite
