Version Number Attacks in RPL based IoT Networks State of the Art and Future directions

The Routing Protocol for Low-Power and Lossy Networks (RPL) faces various challenges, including resource constraints and security threats. Notably, RPL-based environments are susceptible to attacks such as version number attacks due to the limited security measures in the original protocol. Over the years, extensive research has been conducted to address and mitigate these vulnerabilities, with several detection methods proposed using techniques like blockchain, machine learning, and intrusion detection algorithms. This paper focuses on version number attacks in RPL-based IoT networks, reviewing recent and relevant studies that address this issue and propose detection and mitigation frameworks. Additionally, it highlights the challenges and outlines future research directions in securing RPL networks.
