Research ArticleOpen accessEvery word in the titleDETECTING MULTIPLE INTRUSION ATTACKS USING PERMANENT GIRTH CLUSTERING MODEL IN WIRELESS SENSOR NETWORKG. Jayamurugan, P. KamalakkannanSecurity is the central challenge and one of the serious concerns for designing reliable sensor networks. Of the different types of security threats in wireless sensor network, particularly dangerous attack is the replica node attack, in which the opponent takes the secret keying materials from a compromised node. It then produces large number of attacker-controlled replicas that divide up the … …Journal of Computer Science, Vol. 10, Issue 8 · 1 Apr 2014 · 6,467 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDENIAL OF SERVICE ATTACK IN DISTRIBUTED WIRELESS NETWORK BY DISTRIBUTED JAMMER NETWORK: A BIRTH-DEATH RANDOM PROCESS ANALYSISR. Dhanasekaran, G. SingaravelLarge number of low power, tiny radio jammers are constituting a Distributed Jammer Network (DJN) is used nowadays to cause a Denial of Service (DoS) attack on a Distributed Wireless Network (DWN). Using NANO technologies, it is possible to build huge number of tiny jammers in millions, if not more. The Denial of Service (DoS) attacks in Distributed Wireless Network … …Journal of Computer Science, Vol. 10, Issue 8 · 7 Mar 2014 · 6,802 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECTIVE BLACK HOLE ATTACKS IN MANETSRaja Azlina Raja Mahmood, Zurina Mohd Hanapi, Sazlinah Hasan, AsadIqbal KhanBlack hole or packet drop attack is a denial of service attack on routing protocols in which malicious nodes fabricate routing information, attract packets routed through them and then deliberately drop these packets. Most of the black hole attack simulations are performed by constantly fabricating routing information and thus consistently attracting packets to them, which can be easily detected by … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,932 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Proficient Traceback Approach Using Provincial Locality Aspects to Eliminate Denial of Service AttacksS. Periyasamy, K. DuraiswamyA Denial-of-Service (DoS) attack, a menace to the availability of resources and service to the intended user, is usually by augmenting the traffic in the communication medium. These attacks originate in either ways, internal or external to a network with the aim to suspend the legitimate user from getting his/her service. The DoS attacks have been countered through various approaches, … …Journal of Computer Science, Vol. 9, Issue 2 · 12 Apr 2013 · 6,026 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrust Based Node Replication Attack Detection Protocol for Wireless Sensor NetworksV. Manjula, C. ChellappanThe harmful attack against Wireless Sensor Networks (WSN) is Node Replication attack, where one or more node(s) illegitimately claims an identity, are also called clone attack due to identity theft. The Node replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, This study proposes a method Randomized and … …Journal of Computer Science, Vol. 8, Issue 11 · 5 Nov 2012 · 6,756 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparing the Impact of Black Hole and Gray Hole Attacks in Mobile Adhoc NetworksUsha, BoseMobile Adhoc Networks (MANETs) are dynamic in nature. Any nodes can join and leave the network at any time. Hence any type of intruders can attack the communication at any time, especially the routing mechanism between the nodes. In this study, we study and understand two types of attacks which cause more damage to the routing performance of MANET; the … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Sep 2012 · 6,904 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFlooding Distributed Denial of Service Attacks-A ReviewKhadijah Wan Mohd Ghazali, Rosilah HassanProblem statement: Flaws either in users’ implementation of a network or in the standard specification of protocols has resulted in gaps that allow various kinds of network attack to be launched. Of the kinds of network attacks, denial-of-service flood attacks have caused the most severe impact. Approach: This study reviews recent researches on flood attacks and their mitigation, classifying such … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,847 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Sybil and Wormhole Attacks in Location Based Geographic Multicast Routing Protocol for Wireless Sensor NetworksShyamala Ramachandran, Valli ShanmuganProblem statement: Wireless sensor networks have been used in many applications, such as home automation, military surveillances and entity tracking systems. The sensor nodes have low computational capabilities and are highly resource constrained. Routing protocols of wireless sensor networks are prone to various routing attacks, such as black hole, rushing, wormhole, Sybil and denial of service attacks. Approach: The objective … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,982 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAmelioration of Attack Classifications for Evaluating and Testing Intrusion Detection SystemMohammed Saber, Toumi Bouchentouf, Abdelhamid Benazzi, Mostafa AziziProblem statement: The problem of the computer attack system has recently been much studied to improve the evaluation process of the Intrusion Detection Systems (IDS). Approach: This study aimed at presenting the principal attacks classifications; especially, the study of classification towards the evaluation for which we suggested some improvements that may allow the generation of a test cases selection about … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEmpirical Analysis of Virtual Carrier Sense Flooding Attacks Over Wireless Local Area NetworkMina Malekzadeh, Abdul Azim Abdul Ghani, Jalil Desa, Shamala SubramaniamProblem statement: Wireless Local Areas (WLANs) are subject to different types of vulnerabilities. Denial of Service (DoS) attack is the most current challenging issue on the WLANs. The objectives of the study were to (i) Provide an empirical analysis to conduct a series of wireless virtual carrier sense DoS attacks using wireless control frames vulnerabilities, (ii) Design a testbed to … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,650 accessesView PDFCite
