“…This might imply that the equilibrium in a dynamic game is somehow different from the static one, giving a better upper hand to the adversary, if the receiver cannot change location at will but is limited to adjacent positions. Also, the search space would increase quite rapidly and implies that meta-heuristic search tools would be needed [21].…”

“…At the same time, moving away from a source of noise or changing location to avoid channel fades is a quite natural behavior adopted by real receivers, even those acting without any pretence of optimality [18], [19]; thus, in a game theoretic context, it can be considered as available to a rational player [20]. Finally, we point out that, in mmWave communications, we do not require an advanced adversary to undertake elaborate actions, we can focus on the case where it is merely placing an obstacle to cause blockage to the receiver, which in turn tries to evade it [21].…”

“…However, while some properties of the physical and medium access layers are often used to identify the strategies available to the players, we believe that the physical positioning of the involved nodes is relatively less explored. Some investigations were performed in [5], [21], but only related to jamming. In these papers, positioning was considered as influencing the Bayesian types of the players, and subsequently extended to being an active strategic choice of the receiver to evade the jammer.…”

“…The movement of the users is also addressed in [32] for an adversarial setup, but to evaluate its impact on the secrecy capacity from an information-theoretic perspective, and it is found that a moving eavesdropper is more harmful. Finally, [21] more directly considers the choice of position as a dynamic game between a receiver and an adversary, but the focus is still on jamming as a zero-sum game.…”

Given the importance of line-of-sight in mmWave communications, a strategic adversary can harm a transmission by obstructing the receiver, which in turn can react by trying to move around this hurdle. To expand on this point, we study one such scenario from the perspective of game theory, considering a mobile mmWave receiver and an adversary interacting strategically as players in a zero-sum game, where they want to maximize, or respectively minimize, the spectral efficiency of the communication. To do so, the adversary attempts at screening the receiver's line of sight as an obstacle, while the receiver can move around so as to avoid the blockage. We consider preset distances and the choices available to the players are to change their angular coordinates to go around each other. This is framed as a static game of complete information, for which we numerically find the Nash equilibrium in mixed strategies, drawing some interesting conclusions such as connecting it with the beamforming pattern of the transmitter.

“…Jamming problems are a classic application of game theory to wireless communications [1]- [3]. The quintessential jamming scenario involves a zero-sum game played by two agents, i.e., a legitimate network user, acting as a maximizing player, and a jammer, being the minimizer of the receiver's utility that depends on the transmission's efficiency [4], [5].…”

We study a wireless jamming problem consisting of the competition between a legitimate receiver and a jammer, as a zero-sum game with the value to maximize/minimize being the channel capacity at the receiver's side. Most of the approaches found in the literature consider the two players to be stationary nodes. Instead, we investigate what happens when they can change location, specifically moving along a linear geometry. We frame this at first as a static game, which can be solved in closed form, and subsequently we extend it to a dynamic game, under three different versions for what concerns completeness/perfection of mutual information about the adversary's position, corresponding to different assumptions of concealment/sequentiality of the moves, respectively. We first provide some theoretical conditions that hold for the static game and also help identify good strategies valid under any setup, including dynamic games. Since dynamic games, although more realistic, are characterized by an exploding strategy space, we exploit reinforcement learning to obtain efficient strategies leading to equilibrium outcomes. We show how theoretical findings can be used to train smart agents to play the game, and validate our approach in practical setups.
