L'intertextualité dans les publications scientifiques

La base de données bibliographiques de l'IEEE contient un certain nombre de duplications avérées avec indication des originaux copiés. Ce corpus est utilisé pour tester une méthode d'attribution d'auteur. La combinaison de la distance intertextuelle avec la fenêtre glissante et diverses techniques de classification permet d'identifier ces duplications avec un risque d'erreur très faible. Cette expérience montre également que plusieurs facteurs brouillent l'identité de l'auteur scientifique, notamment des collectifs de chercheurs à géométrie variable et une forte dose d'intertextualité acceptée voire recherchée

A secure method to detect wormhole attack in mobile adhoc network

According to recent advances in wireless telecommunications, the performance and use of wireless technologies has increased extremely. In this study concerned on the Mobile Ad-hoc Network (MANET) is a collection of self-configuring mobile node without any infrastructure. There are different security flaws and attacks on the routing protocols in the MANET. One of the critical threats is the wormhole attacks, which have attracted a great deal of attention over the years. The wormhole attack can affect the performance of different routing protocols. During this attack, a malicious node captures packets from one location in the network, and “tunnels” them to another malicious node at a distant point, which replays them locally. This study presents a review of the most important solutions for counteracting wormhole attacks, as well as presents proposed method on DSR routing protocol for detecting them. The performance of the proposed method was examined through ns-2 simulations. Hence, the results show that proposed method can detect this serious attack in a Mobile Adhoc Network

Who wrote this scientific text?

The IEEE bibliographic database contains a number of proven duplications with indication of the original paper(s) copied. This corpus is used to test a method for the detection of hidden intertextuality (commonly named "plagiarism"). The intertextual distance, combined with the sliding window and with various classification techniques, identifies these duplications with a very low risk of error. These experiments also show that several factors blur the identity of the scientific author, including variable group authorship and the high levels of intertextuality accepted, and sometimes desired, in scientific papers on the same topic
