Research ArticleOpen accessIn the keywordsMultipath Adaptive Packet Dispersion for Voice ApplicationsJ. Faritha Banu, V. RamachandranProblem statement: The quality of Voice over IP applications is decided by the main factors like network capacity and technologies such as codec type, Packet Loss Concealment (PLC) and Forward Error Correction (FEC). Approach: In MPLS networks multiple Label Switched Paths (LSP) are established between MPLS ingress and egress nodes to enhance the network performance and QoS for subscribers. To … …Journal of Computer Science, Vol. 8, Issue 4 · 27 Jan 2012 · 7,716 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtility-based Scheduling Frameworks for Efficient Quality-of-Service Differentiation in a Mixture of Real-time and Non-real-time TrafficsOlalekan Bello, Hushairi Zen, AL-Khalid Othman, Khairuddin Abdul HamidThis paper proposes a utility-based scheduling framework for efficient differentiation of users’ Quality-of-Service (QoS) in a broadband wireless access system involving heterogeneous mixed traffic flows. The utility-based scheduling framework, called Maximum QoS Satisfaction (MQS), is based on three novel Radio Resource Allocation (RRA) techniques; delay-based scheduling policy for Real-Time (RT), minimum-rate-based scheduling policy for Non-Real-Time (NRT) and a throughput-based scheduling … …Journal of Computer Science, Vol. 11, Issue 7 · 19 Oct 2015 · 7,139 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMethodology to Asses Internet Protocol Connection Availability: A Prerequisite For Feasible Video Stream Through Content Delivery NetworksVitor Chaves de Oliveira, Gunnar Bedicks Junior, Cristiano AkamineRecent events have shown that content delivery networks as well as Broadband Providers are failing to provide a continuous service, especially on live video stream transmissions for numerous customers. This study aims to present a Methodology to uninterruptedly measure uplink-downlink of a given IP connection. Based on an open-source assemblage of development and data storage platforms it was programmed a … …Journal of Computer Science, Vol. 11, Issue 2 · 2 Oct 2014 · 6,757 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMinimizing Interference in Wireless Mesh Networks Based Telemedicine SystemMohammad Siraj, Kamalrulnizam Abu BakarProblem statement: It has been always a challenging task for the researchers to incorporate information technology advancements in the medical profession. In order to guarantee a reliable network infrastructure that supports the employment of wireless technology and mobile devices, a hybrid infrastructure that integrates wireless networks with the traditional wired Local Area Networks (LANs) is needed. The wired network will … …Journal of Computer Science, Vol. 8, Issue 8 · 14 Jul 2012 · 8,146 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMetro Access Convergence for Broadband Future Low Energy Consumption NetworksG.M. Tosi Beleffi, E. Leitgeb, G. Incerti et al.Problem statement: In study the impact of the optical technologies and infrastructures on the reduction of the carbon footprint maintaining high level of broadband to the end user is discussed. Approach: Authors analyze the main energy consumers in Core, Metro and Access Networks as well as the topology and the performaces of the EU FP7 SARDANA Project, a long reach … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,646 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDelay Analysis and System Capacity Control for Mobile WiMAX Relay NetworksAnas F. Bayan, Tat-Chee Wan, Sureswaran RamadassProblem statement: WiMAX relay is an emerging cost effective wireless last mile solution for rural and urban broadband Internet access. Approach: One of the key concerns of WiMAX operators is how many users they can support for an access area where the number of users and the amount of data that can be delivered to the end user depends on … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,428 accessesView PDF Cite
