Out-of-Band Wormhole Attack Detection in Manets
Mobile Ad hoc NETworks (MANETs) are prone to a variety of attacks due to their unique characteristics such as dynamic topology, open wireless medium, absence of infrastructure, multi-hop nature and resource constraints. Any node in mobile ad hoc networks operates not only as end terminal but both as an intermediate router and client. In this way, multi-hop communication occurs in MANETs and thus it is a difficult task to establish a secure path between source and destination. The purpose of this paper is overcome a special attack called wormhole attack launched by at least two colluding nodes within the network.
