摘　　要：针对无线传感器网络中的搭便车现象,基于博弈理论建立自私节点惩罚机制。将传感器的可信度分为多个等级,对其进行多策略博弈,使其更加符合无线传感器网络的复杂性特点,从而激励节点对可信合作策略的选取。结果表明,基于博弈理论的无线传感器网络中自私节点惩罚机制可以有效地解决网络中的搭便车问题,从而验证了该惩罚机制的有效性。According to the free-riding problem,this paper establishes a penalty mechanism for selfish nodes based on the game theory. In order to satisfy the complexity of wireless sensor networks, the trust degrees of sensors are divided into multi-level, and we game the multi-strategy to incentive sensors to select the trust cooperative strategy. From the experimental results, it can be seen that this penalty mechanism can solve the free-tiding problem effectively,which verify the effectiveness of the proposed penalty mechanism.
