Research ArticleOpen accessEvery word in the titleTHROUGHPUT ANALYSIS OF AGGREGATION WITH FRAGMENT RETRANSMISSION PLUS QUALITY OF SERVICE SCHEMETeuku Yuliar Arif, Riri Fitri SariAggregation with Fragment Retransmission (AFR) is a scheme designed for frame transmission to increase efficiency at the MAC layer throughput. AFR provides a higher throughput compare to Distributed Coordination Function (DCF) scheme. However AFR scheme did not has QoS service function when compared to DCF scheme. DCF scheme already has contention-based QoS service using Enhanced Distributed Coordination Function (EDCA) scheme. … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,319 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThroughput-Delay Trade-Off for Slotted Aloha Multiple Access with Capture EffectA. Chehri, P. Fortier, P. M. TardifProblem statement: Medium Access Control (MAC) protocols are one of most important research issues in communication and networking. There have been proposed several MAC protocols in wireless as well in wired networks. Approach: ALOHA-based protocol is the simplest one, being able to provide prompt access, reliable channels and support for quality of service. However its limited capacity, low throughput and … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLocation Based Throughput Maximization Routing in Energy Constrained Mobile Ad-hoc NetworkV. Sumathy, P. Narayanasamy, R. PrabhuIn wireless Ad-hoc network, power consumption becomes an important issue due to limited battery power. One of the reasons for energy expenditure in this network is irregularly distributed node pattern, which impose large interference range in certain area. To maximize the lifetime of ad-hoc mobile network, the power consumption rate of each node must be evenly distributed and the over … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,823 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHROUGHPUT AND BIT ERROR RATE ANALYSIS OF LUBY TRANSFORM CODES WITH LOW AND MEDIUM NODAL DEGREE DISTRIBUTIONSI. Joe Louis Paul, S. Radha, J. RajaThis study presents two degree distributions namely low and medium nodal degree distributions aiming to build a low overhead Luby Transform (LT) codes. The motivation is to design a fast encoder/decoder especially for real-time multimedia streaming and multicasting applications using LT codes. The key idea of this study is to restrict the average degree of the transmitted encoded symbols as … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 12 Aug 2014 · 6,614 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeasibility 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 accessEvery word in the titleBER Performance and Data Throughput of Sinusoidal Template-Based Impulse-Radio Ultra Wideband Receivers for Wireless Body Area NetworksMohamad Abou El-Nasr, Heba ShabanWindowed sinusoidal template-based correlator receivers are good candidates for high-data rate low-power Ultra Wideband (UWB) systems. Their performance approaches the performance of optimal detectors and provides low-power consumption. However, the ultra short pulses of UWB technology makes it sensitive to timing-errors. In this paper, the Bit-Error-Rate (BER) performance and maximum allowable data throughput of Equally-Correlated Pulse Position Modulation (EC-PPM) modulation … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 30 May 2013 · 6,503 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpacts 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 accessEvery word in the titleFuzzy Velocity Biased-Ad Hoc on Demand Distance Vector to Improve Throughput in Dynamic Mobile NetworkK. Tamizarasu, M. RajaramProblem statement: With the escalating demand for mobile ad hoc network projects, major challenges to system planners and designers were addressing stability and reliability problems due to frequent change of network topology. Controlling an overhead, which means bandwidth utilization due to control packets, depends on the routing protocol, topology and data traffic. Limiting the network control overheads, of this highly … …Journal of Computer Science, Vol. 8, Issue 2 · 21 Nov 2011 · 7,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHardware Implementation of Higher Throughput Anti-Collision Algorithm for Radio Frequency Identification SystemJahariah Sampe, Masuri OthmanThis paper presents a proposed hardware implementation of Higher Throughput Anti-Collision Algorithm (HTACA) for Radio Frequency Identification (RFID) system. Our proposed HTACA combines a pipeline and a deterministic anti-collision technique in order to enhance its performances. These downlink and uplink operations are concurrently executed during the identification process. The downlink operation is purposely pre-selected a group of tags base on … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,443 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of the Impact of Acidity and Alkalinity on the Microbial Community Structure in Urban RiversDongmei Shen, Cairui Yu, Xinwei Song et al.To address the impact of low-temperature pH on the microbial community structure of river sediment in urban rivers during winter, the sediment of the Pi River was sampled to investigate.
