摘　　要：如何有效优化现有无线传感器网络中Do S/DDo S攻击的防御策略是当前的研究热点问题之一。本文结合目前无线传感器网络中的防御技术,利用博弈论的方法建立模型。该模型通过优化防火墙阈值和针对攻击节点给予惩罚措施的方法,来降低攻击节点的收益,使理性攻击者放弃攻击,从而达到了有效防御Do S/DDo S攻击的目的。最后实验通过比较现有的防御策略与提出的优化策略,验证了该防御优化策略的有效性,从而达到了防御Do S/DDo S攻击的目的。In Wireless Sensor Networks（ WSNs）,how to defense Do S/DDo S attack efficiently is one of the challenging security problems. This paper combined with the current defense strategies in WSNs,establishes the model based on game theory. This model prevents malicious nodes from Do S/DDo S attack by optimizing the threshold of firewall and giving malicious nodes punishment,which lower the income of the malicious nodes. Finally,the experiments further verify the efficiency of the proposed optimized defense strategies by comparing the present defense strategies and the optimized ones,to achieve the purpose of preventing Do S/DDo S attack.
