Evaluation of attack effect in ad Hoc networks based on variable weight TOPSIS method

Abstract

Evaluation of Attack Effect in Ad Hoc networks is one of the key technologies for Ad Hoc network security applications. In order to solve the traditional attack effect evaluation with the constant weighted summation can't adjust the relevant weights in time to the change of the attack situation, which causes the limitation and one-sidedness of the judgment. This paper proposes an attack effect evaluation model based on variable weight theory. First, comprehensively considering the relevance of the attack's own complexity and the attack effect, establish an attack effect evaluation indicator system. Then, construct a state variable weight vector expression, so that the weights are adjusted accordingly with the change of the situation. Finally, combined with TOPSIS method, the attack effect evaluation model based on variable weight TOPSIS is constructed. The experimental simulations show that the evaluation results obtained by the model are scientific and reasonable, which makes up for the deviation caused by the decision of the constant weight, and provides a theory and method for the evaluation of the attack effect in Ad Hoc network.
