Research ArticleOpen accessIn the abstractMPLS Based Architecture for Mobility and End-to-End QoS Support in Fourth Generation Mobile NetworksAlejandro Quintero, Eduardo Del FrutosProblem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Medium Access Schemes in 802.11 Wireless NetworksG. Singh, B. S. SohiProblem statement: Deployment of real time services over 802.11 wireless networks requires quality of service (QoS) differentiation mechanisms for different traffic types. This required investigations into the performance of the Medium access (MAC) schemes like Distributed Coordinated Function (DCF) and Enhanced DCF with respect to the stringent QoS requirements imposed by the real time services. Motivation for this research was … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 7,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a High-Performance IP Switching ArchitectureHattab Guesmi, Belgacem Bouallegue, Ridha Djemal, Rached TourkiIn this study we present the architecture for use in high-performance switching networks with support quality of service (QoS) guarantees. Quality of services guarantees in terms of delay, through-put and loss rate can be provided by using mechanism's support like scheduling and buffer management at switching architecture in packet switching networks. Our architecture is based on a new data structure … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Advance Approach to Evaluate the Performance of the TCP NetworksIbrahiem M.M. El Emary, Farouq Al TaweelIn this study, we present a new approach for estimating the performance of the TCP network depending on a mathematical formula which converts the conceptual performance parameter to a valuable one. With respect to TCP network performance, we consider the Random Early Detection (RED) and RED-Based algorithms where both RED and RED-Based follow the Active Queue Management (AQM) approach in … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractTPAL: A Protocol for Node Authentication in IoTMohamad Faiz Razali, Mohd Ezanee Rusli, Norziana Jamil, Salman YussofSecure communication in Low power and Lossy Network (LLN) requires the authentication of the identities of nodes for that node to join the network. Since LLN may consist of many different nodes, where some nodes may contain sensitive and subtle information such as military data, monitoring data, or health data, that node needs to be authenticated before it can deliver … …Journal of Computer Science, Vol. 14, Issue 10 · 30 Oct 2018 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach for Detecting Attacks in Mobile Adhoc NetworksV. Madhu Viswanatham, A. A. ChariThe security of data becomes more important with the increased use of commercial applications over wireless network environments. We presented an approach to handle various attacks for wireless networks. There were several problems of security in wireless networks due to intruders and different type of attacks such as Node Isolation, Route Disruption and Resource Consumption. There were better methods and … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 6,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroducing Song Form Intelligence into Streaming AudioKevin CurranWhen receiving streaming media over a low bandwidth wireless connection, users can experience not only packet losses but also extended service interruptions. These dropouts can last for as long as 15 sec. During this time no packets are received and if not addressed, these dropped packets cause unacceptable interruptions in the audio stream. A long dropout of this kind may … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,572 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNEW 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 accessAll words, across the recordAdaptive Data Transmission in Multimedia NetworksManimegalai Parry, N. GangatharanThis study suggests a method where the packet size of each source is adjusted according to the network bandwidth. A controller is used to trace the data transmission rate at the router. An algorithm is developed and coded in Tool Command Language. Simulation is performed on NS-2 using 4 different test cases and the results show that the proposed algorithm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,246 accessesView PDFCite
