In recent years, the Internet of Things (IoT) has witnessed significant growth, finding applications in smart cities, healthcare, and smart agriculture. The RPL protocol serves as the cornerstone for routing IPv6 packets within IoT networks that have limited resources and unreliable links, while the Objective Function (OF) forms the basis for parent node selection within the DODAG structure.
However, the nature of IoT networks and their deployment in open environments have made them attractive targets for attackers seeking to drain network resources, with the black hole attack considered one of the most critical threats.
In this study, we evaluated the performance of RPL-Based IoT networks under black hole attacks, applying several network-layer protocols to assess their ability to resist such attacks. Simulation results using Octave showed a significant degradation in network performance when using OF0-based RPL and MRHOF-based RPL, with packet loss increasing by 50% and throughput dropping to nearly half.
Conversely, the SecTrust-RPL and SMTrust protocols maintained strong performance, limiting packet loss to around 2%, which improved throughput and demonstrated their effectiveness in detecting malicious nodes and mitigating the impact of black hole attacks.
