Direct Collaborative Attacks on MANET: Network Security - Softcover

Inhaltsangabe

A Mobile Ad hoc Network (MANET) consists of a set of communicating wireless mobile nodes or devices that do not have any form of fixed infrastructure or centralized authority. The security in MANET has become a significant and active topic within the research community. This is because of high demand in sharing streaming video and audio in various applications, one MANET could be setup quickly to facilitate communications in a hostile environment such as battlefield or emergency situation likes disaster rescue operation. As a result of no centralized authority it is prone various collaborative attacks. This study focuses on wormhole attack which is one of the most sophisticated and severe attacks in MANET. In this attack, a pair of colluding attackers record packets at one location and replay them at another location using a private high speed network. In this the colluding nodes create an illusion that two remote regions of a MANET are directly connected through nodes that appear to be neighbours but are actually distant from one another.
