A Bibliometric Analysis of Blockchain Use for the RPL Technology: A Systematic Literature Review

Joshua Teddy Ibibo

Abstract: Internet of Things (IoT) has been the most emerging technology in the last two decade because the number of smart intelligent sensors and its associated technologies has rapidly grown in both industrial and research prospectives. Recent trends have suggested convergence to WSNs becoming IPv6based. To this effect, the ROLL working group of the IETF is currently specifying an IPv6based unicast routing protocol for WSNs, denoted IPv6 Routing Protocol for Low power and Lossy Networks (RPL) of low power consumption, and other constraints of nodes in the network. In this study, we performed a Systematic Literature Review, evaluate, and identify the security issues that exist in the RPL network. Second, identity the use of blockchain technology in protecting the nodes in RPL network. Thirdly, as per blockchain technology, we provide some security solutions and provide robot blockchain taxonomy. The detailed analysis, including enabling technology and integration of IoT technologies, is explained. We review relevant works that have proposed Blockchain based solution to strength the security of RPL network. We further contribute to present, analyze, and compare best authentication solutions. Also, we present the solutions that integrate Blockchain. Finally, several research directions and open challenges are identified.
