Research ArticleOpen accessIn the keywordsData Path Management Mechanism to Mesh Base Stations in WiMAXSahar Abdul Aziz Al-Talib, Noor Raad SaadallahThree options are popular today for design of wireless networks - Point-to-Point, Point-to-Multipoint and Mesh topologies. Worldwide interoperability of microwave access (WiMAX) is most often associated with the point-to-multipoint (PMP) topology. For some requirements, the configuration of the base stations (BSs) is aimed to be as mesh. Mesh offers a combination of point-to-point and point-to-multipoint capability by having each of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 22 Mar 2019 · 7,972 accessesView PDF Cite

Technical ReportOpen accessIn the keywordsEffects of Design Factors of HDFS on I/O PerformanceHan-Gyoo KimFour major design factors of HDFS, the block size, the number of data nodes, the number of client processes and replication factor are investigated to find out the effects on the I/O performance of HDFS by performing experiments in a real physical HDFS infrastructure consisting of 64 Hadoop data nodes of Intel i9 based blades. The block size is observed … …Journal of Computer Science, Vol. 14, Issue 3 · 13 Mar 2018 · 7,987 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCoupling Routing Algorithm and Data Encoding for Low Power Networks on ChipMaurizio Palesi, Davide Patti, Giuseppe Ascia et al.The routing algorithm used in a Network-on-Chip (NoC) has a strong impact on both the functional and non functional indices of the overall system. Traditionally, routing algorithms have been designed considering performance and cost as the main objectives. In this study we focus on two important non functional metrics, namely, power dissipation and energy consumption. We propose a selection policy … …Journal of Computer Science, Vol. 11, Issue 3 · 4 May 2015 · 6,928 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsREVIEW CLUSTERING MECHANISMS OF DISTRIBUTED DENIAL OF SERVICE ATTACKSWesam Bhaya, Mehdi Ebady ManaaDistributed Denial of Service attacks (DDoS) overwhelm network resources with useless or harmful packets and prevent normal users from accessing these network resources. These attacks jeopardize the confidentiality, privacy and integrity of information on the internet. Since it is very difficult to set any predefined rules to correctly identify genuine network traffic, an anomaly-based Intrusion Detection System (IDS) for network … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,635 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Hybrid Speech Recognition System with Hidden Markov Model and Radial Basis Function Neural NetworkJudith Justin, Ila VennilaWe analyze the performance of continuous speech recognition of a speaker independent system using Hidden Markov Model and Artificial Neural Network. Modern speech recognition systems use different combinations of the standard techniques over the basic approach to improve performance accuracy. One such combination which has gained more attention is the hybrid model. Our hybrid system for continuous speech recognition consists … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 6,819 accessesView PDF Cite
