Prevention of Wormhole Attack Using Mobile Secure Neighbour Discovery Protocol in Wireless Sensor Networks

Wireless sensor networks (WSNs) are vulnerable to various types of attacks, and one of them is the wormhole attack. The wormhole attack can severely damage the network by creating a tunnel between two distant nodes, enabling attackers to bypass the normal network routes and steal sensitive information. In this project, we proposed a prevention mechanism for the wormhole attack using the Mobile Secure Neighbour Discovery Protocol in WSNs. We implemented our proposed mechanism using the NS2 simulator and evaluated its performance against the wormhole attack. Our proposed mechanism uses a unique secret key between nodes to prevent attackers from creating a tunnel between them. By tracking the amount of time it takes for the messages to arrive at their destination, we implemented the Mobile Secure Neighbour Discovery Protocol in our system to look for wormhole attacks. Our simulation results show that our proposed mechanism is effective in preventing the wormhole attack in WSNs. It successfully detects and isolates the malicious nodes responsible for the attack, thereby ensuring the security and reliability of the network. Moreover, the proposed mechanism incurs minimal overhead and does not affect the network's performance. Our findings indicate that our proposed mechanism can be a useful tool for securing WSNs against the wormhole attack. And it enhanced network throughput, packet delivery ratio, false detection ratio, and reduced the delay, energy efficiency, and overhead.
