WSN 中基于博弈理论的入侵检测研究

传统的无线传感器网络(wireless sensor networks,WSN)入侵检测研究主要关注检测系统自身算法的设计与优化,而入侵检测系统在采取行动时,本身会受到攻击者的影响.针对这一问题,运用博弈理论建立了一个带惩罚机制的博弈模型,分析了检测系统与入侵者之间的攻防博弈过程.同时对入侵者施加合适的惩罚力度来遏制入侵行为.仿真结果表明,该方案可以有效检测到无线传感器网络中存在的异常节点,并有效降低入侵者的攻击频率.

Intrusion detection based on game theory in wireless sensor network

In recent years, with the rapid increase in the number of war drama creations, excellent works come forth in large numbers, at the same time, there also is shoddy dramas full of screens, but low in artistic and aesthetic level, which not only unsatisfies the aesthetic needs of the audience, and thus results in the different route contrary to the laws of artistic creation, but also misleads the audience into the understanding of the anti-Japanese war history. In order to steer anti-Japanese drama art into the right aesthetic direction, and avoid the artistic image of oversimplification and vulgarization, the following rules should be followed, the first thing is to follow the method of combining the grand narrative artistic expression with microscopic narrative one; the second is to deal well with harmonic and unifying relationship between artistic reality and historical truth; the third thing is to carry forward national spirit of universal perseverance and self-reliance in anti-Japanese war, and highlight the contribution of the grassroots-heroes in the war. In doing so, we can improve continuously art force of the television drama art for anti-Japanese war in broad artistic connotation through the national struggle, carry forward the Chinese nation''s spirit in the great anti-Japanese war, and educate and inspire future generations into unforgetting history, bearing in mind the lessons learned in the great anti-Japanese war, innovation, and strengthening our nation.
