A New Hybrid Algorithm to Eliminate Wormhole Attack in Wireless Mesh Networks

Abstract

Wireless Mesh Network (WMN) is one of the most vibrant field among different wireless communication network technologies. WMN can replace wireless infrastructure network. Self-organization, self-configuring and self-healing natures of WMN dynamically provide solution for high-speed internet access. WMN is highly cost-effective and provides scalability and flexibility. As a result of its open medium nature, distributed architecture and dynamic topology, it is highly prone to security vulnerability. Wormhole attack is the most vulnerable attack in WMN, where two malicious nodes at different locations establish a tunnel between them and can selectively drop data packets. Passed by. Detection and prevention of wormhole attack is very difficult. In this present work, a hybrid algorithm is proposed that can detect and prevent the wormhole attack and also wormhole link is successfully isolated from the concerned network.
