Research ArticleOpen accessEvery word in the titleAn Approach for Detecting Attacks in Mobile Adhoc NetworksV. Madhu Viswanatham, A. A. ChariThe security of data becomes more important with the increased use of commercial applications over wireless network environments. We presented an approach to handle various attacks for wireless networks. There were several problems of security in wireless networks due to intruders and different type of attacks such as Node Isolation, Route Disruption and Resource Consumption. There were better methods and … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 6,928 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc NetworksR. Asokan, A. M. Natarajan, A. NivethaQuality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,671 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Algorithm and Tabu Search Attack on the Mono-Alphabetic Substitution Cipher in Adhoc NetworksA. K. Verma, Mayank Dave, R. C. JoshiWith exponential growth of networked system and application such as e-Commerce, the demand for effective Internet security is increasing. Cryptology is the science and study of systems for secret communication. In consists of two complementary fields of study: cryptography and cryptanalysis. This study presents a cryptanalysis method based on Genetic Algorithm and Tabu Search to break a Mono-Alphabetic Substitution Cipher … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,257 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEVALUATING AN AUTHENTICATED TRUST BASED ADHOC ON DEMAND DISTANCE VECTOR FOR MALICIOUS NODES ISOLATION IN MANETA. Sumathi, B. Vinayaga SundaramMANET networks are defined as the wireless self configuring networks that are capable of operating without the support of any fixed infrastructure and a central coordinator which makes the routing a complicated task. For detecting misbehaving and selfish nodes between the intermediate nodes it is essential to evaluate the Intermediate Trust Value (ITV) for each node in the network, so … …Journal of Computer Science, Vol. 10, Issue 9 · 30 Apr 2014 · 6,789 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGROUP MANAGEMENT IN MOBILE ADHOC NETWORKSK. Senthil Kumar, S. Sasi Kumar, C. SugapriyaIn this study, we proposed an algorithm for Cluster Based Zone Allocation method (CBZA) for energy conservation and packet dropping in mobile ad hoc network. MANET is a self-organized, temporarily dynamic network and their nodes are mobile without using any infrastructure. However, secure communication occurs between group nodes based on cluster method. In multicast routing, group information is shared by … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 22 Apr 2014 · 6,326 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePERFORMANCE ANALYSIS OF ADHOC ON DEMAND DISTANCE VECTOR PROTOCOL WITH BLACKHOLE ATTACK IN WSNMuhammad Ibrahim Channa, Kamalrulnizam Abu Bakar, Adnan AhmedThe security is major challenging issue in wireless sensor network applications because they are operated in public and unrestrained areas which also makes difficult to protect against tampering or captured by an adversary force that can launch insider attacks to make a node compromised. One type of such attack is black hole attack. Existing AODV routing protocol does not have … …Journal of Computer Science, Vol. 10, Issue 8 · 26 Feb 2014 · 7,593 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Dynamic Approach for Rate Adaptation in Mobile Adhoc NetworksPalaniammal Senniappan, Suganya SubramaniamA Mobile Ad hoc Network (MANET) is a collection of mobile nodes with no fixed infrastructure. The absence of central authorization facility in dynamic and distributed environment affects the optimal utilization of resources like, throughput, power and bandwidth. Rate adaptation is the key technique to optimize the resource throughput. Some recently proposed rate adaptations use Request to Send/Clear to Send … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,678 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCluster Based Data Consistency for Cooperative Caching over Partitionable Mobile Adhoc NetworkP. Kuppusamy, B. KalaavathiProblem statement: Data availability and consistency are foremost issues in Mobile Ad hoc Networks due to the absence of permanent infrastructure. Cooperative caching addresses the data availability issue through coordinating the mobile nodes and sharing the cache copies among them. In the meantime, the mobile node must ensure the staleness of cache copies. The consistency maintenance resolves the staleness of … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 10 Jul 2012 · 6,858 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Fault Tolerant Congestion Aware Routing Protocol for Mobile Adhoc NetworksG. Rajkumar, K. DuraiswamyProblem statement: The performance of ad hoc routing protocols will significantly degrade when there are faulty nodes in the network. Packet losses and bandwidth degradation are caused due to congestion and thus, time and energy is wasted during its recovery. The fault tolerant congestion aware routing protocol addresses these problems by exploring the network redundancy through multipath routing. Approach: In … …Journal of Computer Science, Vol. 8, Issue 5 · 23 Feb 2012 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQUEUEING MODELS IN MOBILE AD-HOC NETWORKSS. Baskar, S. PalaniammalThe Mobile Ad-hoc Networks (MANETs) has gain an essential part of the attention of researchers and become very well-liked in last few years. MANETs can operate with no fixed communications and can live rapid changes in the network topology. They can be studied officially as graphs in which the set of boundaries varies in time. One of the main methods … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 26 Dec 2013 · 6,823 accessesView PDFCite
