论文摘要
我们认为，在干扰器的存在下，传感器对通过无线通道进行通信，该干扰器可能会引发拒绝服务攻击。我们在共同设计传输和估计策略的协调员之间制定了零和游戏。我们考虑两种情况，具体取决于干扰器是否可以感知频道。当干扰器无法感知通道时，我们表征了对称和单峰概率密度函数的鞍点平衡。如果干扰器可以感觉到是否使用了通道，我们提供了一种有效的算法，该算法在投影梯度上升的迭代和凸 - 孔concave程序之间交替，以找到近似的一阶NASH-均衡器。我们的数值结果表明，在某些情况下，干扰器可能会决定发动拒绝服务攻击，即使传感器决定不传输，也是欺骗接收器的目标。
We consider a sensor-receiver pair communicating over a wireless channel in the presence of a jammer who may launch a denial-of-service attack. We formulate a zero-sum game between a coordinator that jointly designs the transmission and estimation policies, and the jammer. We consider two cases depending on whether the jammer can sense the channel or not. We characterize a saddle-point equilibrium for the class of symmetric and unimodal probability density functions when the jammer cannot sense the channel. If the jammer can sense if the channel is being used, we provide an efficient algorithm that alternates between iterations of Projected Gradient Ascent and the Convex-Concave Procedure to find approximate First-order Nash-Equilibria. Our numerical results show that in certain cases the jammer may decide to launch a denial-of-service attack with the goal of deceiving the receiver even when the sensor decides not to transmit.
