A Groundbreaking Approach to Counter Blackhole Attacks in RPL

By connecting our physical environment to computer-based systems, the Internet of Things (IoT) decreases human intervention and boosts productivity across a range of sectors, including manufacturing, smart cities, agriculture, automotive, and healthcare. Fitness tracking devices, Bluetooth, and near-field communications (NFC) are changing the Internet of Things environment and affecting many different types of enterprises. However, there are significant privacy hazards associated with the network of IoT devices, which emphasizes the need for reliable network security solutions and legal and secure data packet routing techniques. Additionally, IoT networks are susceptible to both internal and external attacks due to resource constraints, necessitating a careful review of safety assurance measures and enhancement of trust mechanisms, like the Routing Protocol for Low Power and Lossy Networks (RPL), to protect against blackhole intrusion while maintaining the functioning of the protocol. This research presents an enhanced mechanism for that using the Refined Optimal Trust Factor (ROTF) algorithm.
