Ad Hoc networks don't require any infrastructure,and have continuous self-configuration capabilities,which are more in line with the actual situation of mobile device networking.Therefore,they are increasingly used in military activities,disaster relief and intelligent transportation.However,due to the dynamic topology of Ad Hoc networks and the lack of clear network boundaries,it is easier to face various types of attacks,such as eavesdropping,counterfeiting and tampering,and suffer from greater security threats.Therefore,in order to enhance the anti-attack and defense capability of the Ad Hoc network and ensure the secure operation of the network,it is necessary to further evaluate the attack effect based on a large number of attack tests on the Ad Hoc network.The evaluation results can not only test the effectiveness and superiority of the specified attack scheme,but also evaluate the security of the network through simulated attacks,thereby improving the protection capability of the network.This paper proposes an evaluation model of Ad Hoc network attack based on variable power TOPSIS,which combines the traditional network attack effectiveness evaluation technology and the research on the security vulnerability of Ad Hoc network and the possible network attack effect.Firstly,on the basis of studying the characteristics and security threats of Ad Hoc network,considering the correlation between the complexity of the attack and the attack effect,the attack effectiveness evaluation index system for Ad Hoc network is established in this paper.Secondly,in determining the constant rights of indicators,this paper proposes a combination of network analysis method(ANP)and analytic hierarchy process(AHP)based on attack process to solve the influence of the correlation between indicators on the weight of indicators.On this basis,the state variable weight vector applicable to the evaluation is proposed in this paper,so that the index weight is adjusted accordingly with the change of the attack situation to compensate for the deviation caused by the normal power evaluation.Then,this paper proposes an attack effectiveness evaluation model for Ad Hoc networks based on variable weight TOPSIS on the basis of the above research.The experimental results show that the evaluation results obtained by this model are scientific and reasonable,which provide the theory and method for the evaluation of the attack effect of Ad Hoc network.Finally,this paper designs and implements the Ad Hoc network attack effectiveness evaluation system based on variable weight TOPSIS.The system function,system architecture and core module design and implementation are elaborated,and the function of the system is validated.
