Research ArticleOpen accessIn the abstractAdding Quality of Service Extensions to the Enhanced Associativity Based Routing Protocol for Mobile Ad Hoc Networks (MANET)Ayman Mansour Murad, Bassam Al-MahadeenThis paper described how to discover routes that can satisfy QoS service requirements by using extensions to the Enhanced Associativity Bases Routing Protocol (EABR). These extensions were added to the messages used during route discovery. These extensions specify the service requirements, which must be met by nodes re-broadcasting a route request or returning a route reply for a destination.

Research ArticleOpen accessIn the abstractRecovery in Distributed Systems from Transient and Permanent FaultsM. Aliouat, Z. AliouatThe recovery mechanism from transient fault in distributed systems has been intensively studied in the past, but to our best knowledge, none of these studies has been devoted to cope together with transient and permanent hard faults. Our study devoted to recovery processes in a distributed environment in case of hard faults like transient or permanent. The recovery mechanism we … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Physical Organization of R-Trees Using Node ClusteringF. Sagayaraj Francis, P. ThambiduraiR-Tree is a multidimensional indexing structure that forms basis for all the multidimensional indexing structures based on data partitioning. A number of attempts have been made in the past to improve the performance of R-Tree by manipulating the tree parameters and the data parameters. But hardly any attempt had been made to use external parameters such as disk parameters to … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractSSM: Slot Scheduling Mechanisms in a Multihop Wireless Hotspot NetworkMaan Younis AbdullahOur focus was to determine a "slot" time for message forwarding. To this end, we model the system as a "Queue" where the time for packet forwarding is determined by slot, at different slot range for each relaying node. We also introduced one important reason of the poor performance is the close coupling between medium contention and network congestion. Our … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling for Shakedown Analysis of Offshore StructuresMohammad Javad Fadaee, Hamed Saffari, Ramin TabatabaeiThe shakedown analysis process of an offshore structure having elastic-plastic material presented. The finite element model of the structure has been developed first, and then a simple method has been applied for shakedown analysis using matrix tool. Simplifying the relationships together with applying the theory concepts of shakedown analysis is one of the characteristics of the presented method for practical … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Search Results Using Dynamic Document Seed Reranking AlgorithmAngelina Geetha, A. KannanWe proposed an algorithm to improve the precision of top retrieved documents by re-ordering the retrieved documents in the initial retrieval. To re-order the documents, we first automatically extract key terms and key phrases from top N retrieved documents and generate a document index for each document. Using the standard similarity metrics, a document similarity matrix is generated for these … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Network on Chip resources allocation for QoS ManagementAbdelhamid HELALI, Adel SOUDANI, Jamila BHAR, Salem NASRIThe increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. A network on chip draws on concepts inherited from distributed systems and computer networks subject areas to interconnect IP cores in a structured and scalable way. The main goal pursued is to achieve superior bandwidth when compared to conventional on-chip bus architectures.

Each of which was tested against the ID3 methodology using the HSV data set. Number of leaf nodes, accuracy and tree growing time are three factors that were taken into account. Comparisons between different learning methods were accomplished as they were applied to each normalization method. A new matrix was designed … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 34,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Hybrid Mobile Agent Protocol for Wireless Multihop Internet AccessA. Velmurugan, R. RajaramInternet-based Mobile Ad Hoc Networking (MANET) is an emerging technology that supports self-organizing mobile networking infrastructures. This is expected to be of great use in commercial applications for the next generation Internet users. A number of technical challenges are faced today due to the heterogeneous, dynamic nature of this hybrid MANET. A new hybrid routing scheme AODV_ALMA is proposed, which … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Indexing Technique for Information Retrieval Systems Using Rhetorical Structure Theory (RST)Muhammad Shoaib, Abad Ali ShahEffective information retrieval requires an efficient indexing technique. With the availability of huge volume of information, it has become necessary to capture the semantic of the document, which is almost impossible with the existing techniques. Moreover in the existing technique the weights once assign are remains unchangeable through out the cycle. In this paper an indexing technique assignment using Rhetorical … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 7,406 accessesView PDFCite
