DuraiswamyProblem statement: Network wide broadcasting is an important function in Mobile Ad Hoc Networks (MANET), which attempts to deliver packets from a source node to all other nodes in the network. Broadcasting is often very useful for route discovery, naming, addressing and helping multicast operations in all kinds of networks. For designing broadcast protocols for ad hoc networks, one of … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 7,034 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy Meta Node Fuzzy Metagraph and its Cluster AnalysisD. Gaur, A. Shastri, R. BiswasProblem statement: In this study researchers propose a new fuzzy graph theoretic construct called fuzzy metagraph and a new method of clustering finding the similar fuzzy nodes in a fuzzy metagraph. Approach: We adopted T-norms (Triangular Norms) functions and join two or more T-norms to cluster the fuzzy nodes. Fuzzy metagraph is the fuzzyfication of the crisp Metagraphs using fuzzy … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,955 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Distributed Clustering Algorithm for Mobile Ad-hoc NetworksSahar Adabi, Sam Jabbehdari, Amirmasoud Rahmani, Sepideh AdabiThis paper proposed a new Distributed Score Based Clustering Algorithm (DSBCA) for Mobile Ad-hoc Networks (MANETs).In MANETs, select suitable nodes in clusters as cluster heads are so important. The proposed Clustering Algorithm considers the Battery Remaining, Number of Neighbors, Number of Members, and Stability in order to calculate the node's score with a linear algorithm. After each node calculates its … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,119 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffective Load Metric and Efficient Initial Job Placement for Dynamic Load Balancing in ClusterP. Sammulal, M. V. Gopalachari, A. V. BabuHigh performance clusters are being configured specially to give data centers that require extreme performance and the processing power they need. When the data is accessed across clusters the data latency time has significant impact on the performance. In the literature it is given that memory and I/O have become the new bottleneck, instead of processing power in achieving efficient … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,909 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Head Cluster Election Algorithm for Clustered Ad-Hoc NetworksArwa Zabian, Ahmed Ibrahim, Fadi Al-KalaniIn distributed system, the concept of clustering consists on dividing the geographical area covered by a set of nodes into small zones. In mobile network, the clustering mechanism varied due to the mobility of the nodes any time in any direction. That causes the partitioning of the network or the joining of nodes. Several existing centralized or globalized algorithm have … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 7,437 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpeedup of Particle Transport Problems with a Beowulf ClusterZhongxiang Zhao, G. Ivan MaldonadoThe MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport[1]. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scientists … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Dec 2006 · 6,923 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleDistributed Clusterhead Architecture for Mobile Ad Hoc NetworksEmad Qaddoura, Wesam AlMobaideen, Ahmad OmariMobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. The nodes are grouped in clusters for the purpose of routing. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a clusterhead. An elected clusterhead is assigned for communication … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,809 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRedundancy Schemes for High Availability Computer ClustersChristian K. Bassek, Samuel Pierre, Alejandro QuinteroThe primary goal of computer clusters is to improve computing performances by taking advantage of the parallelism they intrinsically provide. Moreover, their use of redundant hardware components enables them to offer high availability services. In this paper, we present an analytical model for analyzing redundancy schemes and their impact on the cluster’s overall performance. Furthermore, several cluster redundancy techniques are … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,236 accessesView PDFCite
