Research ArticleOpen accessIn the abstractDevelopment of an Energy-Efficient, Secure and Reliable Wireless Sensor Networks Routing Protocol Based on Data Aggregation and User AuthenticationA. Gopi Saminathan, S. KarthikData aggregation protocols are required in Wireless Sensor Networks (WSNs) to improve the data accuracy and extend the network lifetime by reducing the energy consumption. The existing Data Aggregation-Optimal LEACH (DAO-LEACH) protocol for WSN is enhanced in terms of security and fault-tolerance based on Gracefully Degraded Data Aggregation (GDDA) to ensure the integrity of the aggregated data and Hybrid Layer … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,860 accessesView PDFCite
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 · 6,845 accessesView PDFCite
Research ArticleOpen accessIn the abstractE2AODV Protocol for Load Balancing in Ad-Hoc NetworksR. Vinod Kumar, R. S.D. Wahida BanuProblem statement: In mobile ad hoc networks there are a number of challenges in providing quality of service routing with energy efficiency and load balancing. Most routing protocols do not consider the problem of load balance. A routing protocol called energy Efficient Ad-hoc on Demand Vector (E2AODV) is proposed. It addresses the quality of service issues such as throughput, end … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jul 2012 · 6,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination. The major problems of congestion or … …Journal of Computer Science, Vol. 8, Issue 6 · 4 Apr 2012 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn 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 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Buffer Management with Epidemic Routing in Delay Tolerant NetworksG. Fathima, R. S.D. WahidabanuProblem statement: The Design of Delay Tolerant Network (DTN) routing protocols has focused to operate in an environment where there is no guarantee of end to end path between source and destination at all points of time. The DTN research has focussed primarily on applications that are delay tolerant. But it can also be used to provide real time information … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Routing Protocol to Eliminate Integrity, Authentication and Sleep Deprivation Based Threats in Mobile Ad hoc NetworkEdna Elizabeth Nallathambi, Radha Sankararajan, Vaithiyanathan Sundaram, Gracelin SheebaProblem statement: Network security in Mobile Ad hoc Network (MANET) is a major issue. Some of the attacks such as modification, impersonation, Time To Live (TTL) and sleep deprivation are due to misbehaviour of malicious nodes, which disrupts the transmission. Some of the existing security protocols such as ARAN, SAODV and SEAD are basically used to detect and eliminate one … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,822 accessesView PDFCite
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 · 7,059 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterference Mitigation in IEEE 802.15.4-A Cluster Based Scheduling ApproachG. M. Tamilselvan, A. ShanmugamProblem statement: In universal networking environments; two or more heterogeneous communication systems coexisting in a single place. Especially, Wireless Local Area Networks (WLANs) based on IEEE 802.11b specifications and Wireless Personal Area Networks (WPANs) based on IEEE 802.15.4 specifications need to coexist in the same Industrial, Science and Medial (ISM) band. If the WPAN communication coverage is expanded using a … …Journal of Computer Science, Vol. 7, Issue 1 · 15 Jan 2011 · 7,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance 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 · 6,893 accessesView PDFCite
