In this paper, we propose a trustworthy friendly jammer selection scheme with truth-telling for wireless cooperative systems. We first utilize the reverse auction scheme to enforce truth-telling as the dominant strategy for each candidate friendly jammer. Specifically, we consider two auction cases: (1) constant power (CP) case and (2) the utility of the BS maximization (UBM) case. In both cases, the reverse auction scheme enforces truth-telling as the dominant strategy. Next, we introduce the trust category and trust degree to evaluate the trustworthiness of each Helper transmitter (Helper-Tx). Specifically, an edge controller calculates the reputation value of each Helper-Tx periodically using an additive-increase multiplicative-decrease algorithm by observing its jamming behavior. With the historical reputation values, the edge controller (EC) classifies a Helper-Tx into one of four trust categories and calculates its trust degree. Then, the EC selects the best Helper-Tx based on the trust category and trust degree. Lastly, we present numerical results to demonstrate the performance of our proposed jammer selection scheme.

用于无线协作系统的具有可信度的可信赖干扰器选择

在本文中，我们提出了一种具有可信度的可信赖的友好干扰选择方案，用于无线协作系统。我们首先利用反向拍卖方案将讲真话作为每个候选人友好干扰者的主要策略。具体来说，我们考虑两个拍卖案例：（1）恒定功率（CP）案例和（2）BS最大化（UBM）案例的效用。在这两种情况下，反向拍卖方案都将讲真话作为主要策略。接下来，我们介绍信任类别和信任度评估每个Helper发送器（Helper-Tx）的可信度。具体而言，边缘控制器通过观察其干扰行为，使用加减乘减算法定期计算每个Helper-Tx的信誉值。利用历史信誉值，边缘控制器（EC）将Helper-Tx分为四个信任类别之一，并计算其信任度。然后，EC根据信任类别和信任度选择最佳的Helper-Tx。最后，我们给出数值结果来证明我们提出的干扰器选择方案的性能。
