Abstract

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 work is overcome a special attack called wormhole attack launched by at least two colluding nodes within the network. In this paper we enhance AODV to detect and remove wormhole attack in real-world mobile ad hoc networks. In an out-of-band wormhole attack the communication between two malicious nodes is hidden from the rest of the nodes. This property is exploited by our proposed AODV-DRW protocol for the detection of wormhole attack.
