Then, I will introduce how this paper quantifies these tactics , so we can define the utility function of the players.
When the attacker conducts jamming attacks, it is possible for the attack to fail even if the defender does not implement any defensive measures. This can occur because limitations such as jamming power or targeting accuracy prevent the jamming signal from fully covering the defender's communication frequency band.
So we denote the probability of a successful attack by the attacker as mu, when no defensive measures are implemented.
In this article we assume the probability of a successful attack is related to two factors.
One is the probability of the defender successfully detecting the jamming alpha r.
(r represents the index of an attack action in a given attack strategy)
The other one is the probability of a successful defense beta s.
(s denotes the index of a defense action in a given defense strategy)
Furthermore, we consider the attacker gains a payoff Ra when the attack is successful, and gains nothing if the attack fails.
And regardless of whether the attack succeeds or fails, an attack cost Car must be paid.
Therefore, the utility for the attacker when choosing attack action ar can be expressed as this equation. |
