Research ArticleOpen accessIn the abstractAN ENHANCED ROUTE FAILURE RECOVERY MODEL FOR MOBILE AD HOC NETWORKSP. R. Jasmine Jeni, A. Vimala Julie, A. Messiah BoseIn Mobile Ad Hoc Networks (MANET), change in topology of the network occurs due to the mobility factor of the nodes leading to the extension in size of the network. The extension of network size happens due to the entry of nodes into the network. As the topology changes, link failure between the nodes takes place due to several reasons … …Journal of Computer Science, Vol. 10, Issue 8 · 8 Apr 2014 · 6,739 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 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 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
Research ArticleOpen accessIn the abstractAn Analysis of Power Aware Congestion Control Multipath Multicast Protocol for Mobile Ad hoc NetworkDuraiswamy Karuppaswamy, Vijayaragavan ShanmugamProblem statement: In MANETs, wireless link transmission errors, mobility and congestion are major causes for packet loss. Mobility may cause packet loss in different ways. Whereas congestion in a network occurs, whenever the demands exceed the maximum capacity of a communication link especially when multiple hosts try to access a shared media simultaneously. Approach: In this study, we proposed a … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 7,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistory Based Contention Window Control in IEEE 802.11 MAC Protocol in Error Prone ChannelAli Balador, Ali Movaghar, Sam JabbehdariProblem statement: IEEE 802.11 Medium Access Control (MAC) protocol is one of the most implemented protocols in this network. The IEEE 802.11 controls the access to the share wireless channel within competing stations. The IEEE 802.11 DCF doubles the Contention Window (CW) size for decreasing the collision within contending stations and to improve the network performances but it is not … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Jul 2010 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Assessment of Meat Qualities of Purebred and Crossbred Kalmyk BullsI. N. Aitzhanova, G. I. Shaikamal, L. A. Seleuova et al.The purpose of thisstudy was to review the meat qualities of Kalmyk cattle by the method oflifetime evaluation of the meat forms of purebred and crossbred bulls bystudying growth and development, as well as determining the thickness ofsubcutaneous fat, the loin eye area and the meat marbling. Throughout theexperiment (from 6 to 12 months), Kalmyk bulls were characterized bysignificantly (p≤0.01) … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 20 Sep 2022 · 5,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Rearing Method and Varying Energy Levels on Performance and Growth Rate of Male Kamang DucksSabrina, Husmaini, Firda Arlina, Linda SuhartatiThis study was conducted to determine the performance of male Kamang ducks reared with pools and without pools with three different levels of ration energy.
