GIDPS: A game theory-based IDPS for RPL-networked low power lossy networks with energy limitation

Due to the resource-constraint features of LLNs and inherent vulnerabilities of RPL, the security design of deploying Intrusion Detection and Prevention System (IDPS) is widely used. However, IDPS has large energy consumption which is a major concern of LLNs. In order to protect LLNs and save energy resources, we propose an energy-efficient IDPS scheme using game theoretic framework, which analyze interactions with attackers and take the best optimal prevention action with least cost. Simulation analysis prove that the proposed scheme could effectively reduce the cost caused by prevention attacker and thereby prolong the lifecycle of nodes.
