Solving decreased rank in rpl attack: the ethereum blockchain approach

The routing protocol of nodes in RPL networks will now use a safe blockchain-based authentication system, according to this study. The Ethereum blockchain and smart contracts are used in the suggested approach to address the security issues, notably Decreased Rank At-tack in RPL network topology. The background of RPL, IoT-LLNs, and blockchain technology is covered in the study, along with the suggested methodology and its application. The study also assesses the performance of the suggested remedy and contrasts it with current approaches.
