Research ArticleOpen accessAll words, across the recordSurvey on Mobile Ad Hoc Network Attacks and Mitigation Using Routing ProtocolsS. P. Manikandan, R. ManimegalaiMobile Ad hoc Networks (MANET) due to its unpredictable topology and bandwidth limitations are vulnerable to attacks. Establishing security measures and finding secure routes are the major challenges faced by MANET. Security issues faced by ad hoc networks are node authentication, insider attack and intrusion detection. Implementing security measures is challenging due to the presence of limited resources in the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 6,851 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImpact of Malicious Nodes under Different Route Refresh Intervals in Ad Hoc NetworkP. Suganthi, A. TamilarasiProblem statement: Ad hoc networks are formed dynamically by group of mobile devices co operating with each other. Intermediate nodes between source and destination act as routers so that source node can communicate with the destination node even if it is out radio range and thus eliminating the necessity of infrastructure. Co operation of nodes is a very important feature … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 7,302 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Optimal Path Management Strategy in Mobile Ad Hoc Network Using Fuzzy and Rough Set TheoryP. Seethalakshmi, M. Joseph Auxilius Jude, G. RajendranProblem statement: Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes that dynamically forms a network. Most of the existing ad-hoc routing algorithms select the shortest path using various resources. However the selected path may not consider all the network parameters and this would result in link instability in the network. The problems with existing methods are … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,667 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPerformance Study of Threshold Variations in Temporal Decision Systems for Routing in Vehicular Ad hoc NetworksB. S. Shylaja, V. Mary Anita Rajam, V. Uma Maheswari, Arul SiromoneyProblem statement: Route maintenance and re-discovery are expensive in signaling and computation for routing in Vehicular Ad hoc Networks (VANETs). Hence it was desirable to choose the optimal route during the route selection phase. Approach: In this study, the threshold-based routing protocol β-wt uses the notion of threshold from variable precision rough sets. This protocol was used to evaluate routing … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,890 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDecreasing Overhead and Power Consuming in Ad-Hoc Networks by Proposal a Novel Routing AlgorithmA. Barati, A. Movaghar, H. Barati, A. Azizi MazreahAn Ad-Hoc network has been constructed from a fabric of mobile nodes intercom connected by temporary wireless links. Nodes located beyond a single hop are reached using intermediate neighbors to forward messages over long distances. The problem with this method of communication is that mobility causes the network topology to be unstable. Traditional solutions maintain routes by exchanging information when … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,800 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDistributed 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 · 6,804 accessesView PDF Cite
