Impact of Decreased Rank Attack on Network Topology of RPL Using Contiki-NG

Abstract

The Internet of Things (IoT) refers to the widespread use of smart objects connected to the internet. This innovative technology serves as the foundation for various intelligent gadgets, including smartphones, smart homes, and electric equipment. Furthermore, these devices are uniquely identified and automatically connected to the network. RPL emphasizes security due to the nature of objects and their restrictions, which might pose weaknesses for cyber-attacks. It is crucial to identify and assess all potential assaults on this protocol, including the rank attack, which can significantly impact network performance and energy usage. The impact of rank assaults on the proactive IoT routing protocol, Low Power Lossy Network (RPL), is discussed in this study. It emphasizes the necessity of addressing these attacks concerning different scenarios preserving topology, avoiding communication delays, and reducing throughput. The proposed solution significantly decreases the impact of a decreased rank attack on network performance.
