Research ArticleOpen accessIn the keywordsFault-tolerant Distributed Systems with Diagnostics AlgorithmsOleg Viktorov, Afif MghawishTo provide consistent actions in distributed systems with faulty nodes the Byzantine agreement protocol (algorithm) is widely used. In case of using message exchange scheme without authentication the Byzantine agreement algorithm leads to agreement if the number of nodes doesn’t exceed 1/3 of the total number. The proposed algorithms based on diagnostics procedures are used to reach an agreement in … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,840 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSelfish Scheduler for Packet Scheduling Based on Packet Weighted Energy Drain Rate in ManetsS. Lakshmi, S. RadhaThe aim of our selfish scheduler based on packet weighted energy drain rate in Mobile ad-hoc networks mainly depends on the available least highest-limit of the residual value of a mobile node. The projected work comprises of mechanisms for detecting the selfish node as well as an attitude called rehabilitate-before-malicious behavior for justifying against the malicious behavior of nodes having … …Journal of Computer Science, Vol. 9, Issue 1 · 6 Feb 2013 · 6,842 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAcknowledgment based Reputation Mechanism to Mitigate the Node Misbehavior in Mobile Ad Hoc NetworksK. Gopalakrishnan, V. Rhymend UthariarajProblem statement: The cooperation between the nodes is essential to discover and maintain routes in mobile ad hoc network. Due to the presence of misbehaving nodes, the node cooperation is not always guaranteed as the nodes agreed during the route discovery phase. This phenomenon results in frequent network partitioning and it makes the routing process difficult. It also degrades the … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,567 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Robust Byzantine Fault-Tolerant Replication Technique for Peer-to-Peer Content DistributionAyyasamy Sellappan, Sivanandam NatarajanProblem statement: In peer-to-peer networks, Byzantine fault tolerance refers to the capability of a system to tolerate Byzantine faults. It can be achieved by replicating the server and by ensuring all server replicas reach an agreement on the input despite Byzantine faulty replicas and clients. Since malicious attacks and software errors can cause faulty nodes to exhibit Byzantine behavior, Byzantine-fault-tolerant … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,056 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Combined Solution for Routing and Medium Access Control Layer Attacks in Mobile Ad Hoc NetworksR. Murugan, A. ShanmugamProblem statement: In Mobile Ad hoc Network (MANET), both the routing layer and the Medium Access Control (MAC) layer are vulnerable to several attacks. There are very few techniques to detect and isolate the attacks of both these layers simultaneously. In this study, we developed a combined solution for routing and MAC layer attacks. Approach: Our approach, makes use of … …Journal of Computer Science, Vol. 6, Issue 12 · 4 Nov 2010 · 7,135 accessesView PDF Cite
