Cluster-head Centered Fast Secure Routing based on Game theory for Device-to-Device Communication

The unique distributed architecture of device-to-device (D2D) networks makes its devices and users more vulnerable to security and privacy threats, especially from malware. To protect the D2D network from the malware, we designed and implemented a novel routing protocol, Cluster-head Centered Fast Secure Routing. The protocol requires all of the member nodes to pass data packets through the Secure Routes selected by the cluster-head that optimizes routing decisions to reduces the possibility of the nodes receiving packets with malware. After our analysis, the strategy is the optimal coping strategy of the defender whenever the attacker using the Nash game strategy, the Stackelberg game strategy, considering the case of both zero-sum and the non-zero sum. Moreover, to ensure the security of the cluster-head, we have set up the Mobile Edge Computing servers at the edge of the D2D networks. Simulation results demonstrate that the proposed routing protocol can balance network security and Quality of Service, thus confirming that our proposed routing algorithm has practical significance.
