The Routing Protocol for Low-Power and Lossy Networks (RPL) is a widely applied network layer protocol in IoT. The RPL is vulnerable to several routing attacks due to resource restrictions and internet connection. It necessitates analyzing the RPL routing activities and examining the transitions between nodes to identify the malicious neighboring nodes. One of the best methods to analyze the RPL activities is Game-Theoretic Approach. Game denotes the mathematical models of strategic interactions between IoT devices. They are considered as players in the gaming model.
