自私节点的存在使得MANETs网络的入侵检测性能低下。针对该问题提出一种基于非合作零和博弈的入侵检测模型。一方面，通过建立代价函数和提高信誉的方式激励自私节点积极参与合作，从而选择出最优领导节点，提高群内节点的生存时间；另一方面，建立领导节点IDS和入侵者的非合作博弈模型，利用求解贝叶斯纳什均衡的方法对其进行求解，按照求解结果为节点分配负载，实现对节点资源的合理使用，提高模型对入侵的检测率。

The presence of selfish nodes makes the performance of MANETs network intrusion detection poor .In this paper , we present an intrusion detection model to solve the problem , it is based on the non-cooperative zero-sum game.On the one hand, active participation and cooperation of the selfish nodes are motivated through the establishment of a cost function and the reputation improvement so as to select the optimal leader node and increase the survival time of the nodes in clusters .On the other hand , a non-cooperative game model between the leading node IDS and the intruders is built , and is solved by Bayesian Nash equilibrium method , the loads are then allocated to the nodes according to the results of the solution , this realises the reasonable use of the node resources , and improves the detection rate of intrusion by the model.
