Using Stackelberg game to enhance node protection in WSNs

In this paper, we propose a game-theoretic protection model for Wireless Sensor Network (WSN) nodes within a cluster based on a Stackelberg game. The proposed game approach is developed for two different attack-defense scenarios. In the first scenario, the attacker selects to attack a group of nodes that have a protection degree below a specific threshold. In the second scenario, the attacker targets the nodes that have been reported to be least protected in the previous round. Simulation results indicate the improved performance of the proposed protection model as compared to the no-defense case.
