Networks Attack-Defense model based on the improved Lanchester equation

The computer network Attack and Defense is the important combat activity to get the information superiority in modern and future battlefields. In this paper, we try to apply the Lanchester equation of military confrontation to examine the network attack and defense. First, the network combat concerns are divided into two types according to their combat features, i.e. the point and area attack or defense; and then, an improved Lanchester equation model based on time action factor is proposed by means of combining the Lanchester second linear law with the square law and introducing a time action factor to describe the action of both sides of the combat; finally, some simulation results are given, and the affections of the loss coefficient of the point, area combat and the combat action time on the combat results are discussed to provide the basis for the network combat decision.
