A Wormhole Attack Detection and Prevention Technique in Wireless Sensor Networks

Abstract

Security is one of the major and important issues surrounding network sensors because of its inherent liabilities, i.e. physical size. Since network sensors have no routers, all nodes involved in the network must share the same routing protocol to assist each other for the transmission of packets. Also, its unguided nature in dynamic topology makes it vulnerable to all kinds of security attack, thereby posing a degree of security challenges. Wormhole is a prominent example of attacks that poses the greatest threat because of its difficulty in detecting and preventing. In this paper, we proposed a wormhole attach detection and prevention mechanism incorporated AODV routing protocol, using neighbour discovery and path verification mechanism. As compared to some preexisting methods, the proposed approach is effective and promising based on applied performance metrics.

A Hybrid Wormhole Attack Detection in Mobile Ad-Hoc Network (MANET)

“…Wormhole attack can be classified into four modes of attack operations, which are, packet encapsulation, high power transmission, packet relay and out-of-band. The tunnel can be launched through wired and wireless transmission or an optical link as mentioned in [33], [35]. The packet will be forwarded through distant wormhole nodes by creating an illusion that they are close to each other whereas in reality, they are not.…”
