Research ArticleOpen accessAll words, across the recordSECRET HANDSHAKE ISSUE AND VALIDATE AUTHORITY BASED AUTHENTICATION SYSTEM FOR WIRELESS SENSOR NETWORKKamalanaban Ethala, R. Seshadri, N. G. Renganathan, M. S. SaravananWireless Sensor Networks (WSN) are major research area in the past few decades. WSN is formed by collection of sensor nodes. Power source life and memory size limit the hardware sources and these will decide the lifesapn of sensor nodes in WSN. Therefore, many resources based research issues are evolved in WSN. This study focused security issue and proposed authentication … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,429 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordSECURITY IN VEHICULAR AD HOC NETWORK BASED ON INTRUSION DETECTION SYSTEMOmkar Pattnaik, Binod Kumar PattanayakImplementation of mobile ad hoc networks has eventually captured practically most of the parts of day-to-day life. One variation of such networks represents the Vehicular Ad Hoc Networks (VANETs), widely implemented in order to control day-to-day road traffic. The major concern of VANETs is oriented around providing security to moving vehicles that makes it possible to reduce accidents and traffic … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 27 Dec 2013 · 7,022 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Cyber Space and Information, Communication and Technology: A Tool for Westernization or Orientalism or BothAhmad Rizal Mohd Yusof, Mohamad Fauzi Sukimi, Solahuddin Bin Ismail, Zaheruddin Bin OthmanProblem statement: The role of ICT and cyberspace and their existence have become prevalent popular phenomena to the extent that they are perceived to have the potential for transforming the world and launch it into a Digital era. The advent and advancement of ICT and cyberspace has also facilitated the globalization process and is used as an integrative tool, making … …Journal of Computer Science, Vol. 7, Issue 12 · 15 Oct 2011 · 7,503 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordStrength Pareto Evolutionary Algorithm based Multi-Objective Optimization for Shortest Path Routing Problem in Computer NetworksSubbaraj Potti, Chitra ChinnasamyProblem statement: A new multi-objective approach, Strength Pareto Evolutionary Algorithm (SPEA), is presented in this paper to solve the shortest path routing problem. The routing problem is formulated as a multi-objective mathematical programming problem which attempts to minimize both cost and delay objectives simultaneously. Approach: SPEA handles the shortest path routing problem as a true multi-objective optimization problem with competing … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,216 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSimulation of the Enhanced Associativity Based Routing Protocol for Mobile Ad Hoc Networks (MANET)Ayman Mansour Murad, Bassam Al-MahadeenThe simulations results showed that the overall EABR enhancement, when compared with ABR, in terms of communication overhead was ranging from 36% to 56%. While the overall EABR enhancement in terms of number of operation required to reconstructing the route was ranging from 36% to 55%. These enhancements were contributed to the novel way in route reconstructing introduced by EABR. …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,957 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Enhanced Associativity Based Routing ProtocolSaid A. Shaar, Fawaz A.M. Masoud, Ayman Murad et al.This study introduces an analysis to the performance of the Enhanced Associativity Based Routing protocol (EABR ) based on two factors; Operation complexity (OC) and Communication Complexity (CC). OC can be defined as the number of steps required in performing a protocol operation, while CC can be defined as the number of messages exchanged in performing a protocol operation[1].
