Research ArticleOpen accessIn the keywordsNEW BURST ASSEMBLY AND SCHEDULING TECHNIQUE FOR OPTICAL BURST SWITCHING NETWORKSV. Kavitha, V. PalanisamyThe Optical Burst Switching is a new switching technology that efficiently utilizes the bandwidth in the optical layer. The key areas to be concentrated in Optical Burst Switching (OBS) networks are the burst assembly and burst scheduling i.e., assignment of wavelengths to the incoming bursts. This study presents a New Burst Assembly and Scheduling (NBAS) technique in a simultaneous multipath … …Journal of Computer Science, Vol. 9, Issue 8 · 6 Jul 2013 · 6,944 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Interaction between Congestion-Control Based Transport Protocols and Manet Routing ProtocolsKhuzairi Mohd Zaini, Adib M. Monzer Habbal, Fazli Azzali et al.Problem statement: Although many efforts have been done on studying the behaviour of TCP in MANET, but the behaviour of TFRC remain unclear in MANET. The purpose of this research is two folds. First, we studied the behaviour of TFRC and TCP over AODV and DSR as the underlying routing protocols in terms of throughput, delay and jitter. The second … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy-Based Admission Control Scheme for Voice over IP NetworksSami Alwakeel, Agung PrasetijoProblem statement: In Voice Over IP (VOIP) network, when more calls are admitted to the network, more voice packet traffic is created. Since bandwidth is always limited, this may result network congestion and/or may affect voice quality. Thus, we needed a mechanism for improving the Quality of Service (QoS) by controlling VOIP calls admission. Approach: Given a specified bandwidth and … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,609 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUtility 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 accessAll words, across the recordSecure Enhanced Authenticated Routing Protocol for Mobile Ad Hoc NetworksM. Rajesh Babu, S. SelvanProblem statement: This study propose an improvement of Ad Hoc on Demand Distance Vector (AODV) Routing protocol in order to include some of the aspects of ad hoc networks such as load balancing, congestion avoidance and avoidance of link breakage. Approach: The most important problem nowadays is link breakage which mainly occurs due to excessive load and congestion in the … …Journal of Computer Science, Vol. 7, Issue 12 · 17 Oct 2011 · 6,620 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFuzzy Logic Controller for Wireless Video TransmissionK. P. Rajesh, K. S. RamaswamiProblem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,950 accessesView PDFCite
