An Approach to Improve the Performance of WSN during Wormhole Attack using Promiscuous Mode

Abstract

Due to dynamic topology and non-wired infrastructure of Wireless Sensor Networks (WSN), they are prone to attacks. Wormhole attack is one of the most popular and serious attack in WSNs. In Wormhole attack two or more malicious nodes makes a covert channel which attracts the traffic towards itself by depicting a low latency link and then start dropping and replaying packets in the multi-path route. This paper proposes promiscuous mode method to detect and isolate the malicious node during wormhole attack by using Ad-hoc on demand distance vector routing protocol (AODV) with omnidirectional antenna. This paper proposes that the nodes which are not participating in multi-path routing generates an alarm message during delay and then detects and isolate the malicious node from network.

A Security Scheme against Wormhole Attack in MAC Layer for Delay Sensitive Wireless Sensor Networks

“…When the wormhole attack is present [14], [15], [16] and [17], a malicious node intercepts messages in one part of the network then tunnels them over a low latency link (wired link or a high RF band) and replays them in a different far away part of the network. A typical wormhole attack requires two or more attackers [18] malicious nodes -who have better communication resources than regular sensor nodes [19].…”
