论文摘要
通信网络中状态消息传递的及时性是随着时变的无线通道传输的主观。在本文中，我们在具有主动服务器故障的多源M/g/1排队更新系统中调查了每个源的信息年龄（AOI）。特别是，我们采用补充变量的方法来在系统参数方面得出平均AOI的封闭形式表达式，其中服务器维修时间遵循一般分布，而独立源生成的数据包的服务时间是一般的随机变量。提供数值结果以验证在不同的参数设置下提出的数据包服务策略的有效性。
The timeliness of status message delivery in communications networks is subjective to time-varying wireless channel transmissions. In this paper, we investigate the age of information (AoI) of each source in a multi-source M/G/1 queueing update system with active server failures. In particular, we adopt the method of supplementary variables to derive a closed-form expression for the average AoI in terms of system parameters, where the server repair time follows a general distribution and the service time of packets generated by independent sources is a general random variable. Numerical results are provided to validate the effectiveness of the proposed packet serving policy under different parametric settings.
