The paper discusses the vulnerability of wireless sensor networks (WSNs) to security attacks, particularly focusing on the wormhole attack, which disrupts network routing and can lead to denial of service. It proposes a prevention technique that employs a unique key generation scheme for validating two-hop neighbor nodes during route reply packet forwarding, without requiring additional hardware or time synchronization. The research provides insights into existing methods for wormhole detection and prevention, culminating in a novel approach aimed at enhancing the security of WSNs.
