论文摘要
在这封信中，我们提出了可靠的秘密通信，目的是最大程度地减少随时间变化的渠道中的信息时代（AOI）。我们将通道状态信息（CSI）作为新指标有效的持续时间命名为通道变化的年龄（AOC）。为了在动态环境中以新的方式找到可靠的秘密通信，这项工作考虑了一个新约束，显示了AOI和AOC之间的关系。借助拟议的约束，本文解决了可靠的秘密通信的两个主要挑战，目的是最大程度地减少AOI：1）尺寸理想的用户数据包； 2）保证在随着时变的网络中，威利斯检测的可能性可忽略不计。在仿真结果中，我们比较了可靠的秘密通信中提出的约束的性能，以最大程度地限制AOI，并常规优化Covert Communications信息新鲜度的需求。
In this letter, we propose reliable covert communications with the aim of minimizing age of information (AoI) in the time-varying channels. We named the time duration that channel state information (CSI) is valid as a new metric, as age of channel variation (AoC). To find reliable covert communication in a fresh manner in dynamic environments, this work considers a new constraint that shows a relation between AoI and AoC. With the aid of the proposed constraint, this paper addresses two main challenges of reliable covert communication with the aim of minimizing AoI: 1) users packets with desirable size; 2) guaranteeing the negligible probability of Willies detection, in time-varying networks. In the simulation results, we compare the performance of the proposed constraint in reliable covert communication with the aim of minimizing AoI with conventional optimization of the requirement of information freshness in covert communications.
