我们考虑一个由源-目的通信链路组成的系统。在源的发送端有一个缓冲区,用于存储包含状态信息的数据包。这些随机生成的数据包应该使目的地及时更新,并且可以丢弃,避免传输陈旧信息浪费网络资源。在此设置中,我们分析了系统的信息年龄(AoI)和峰值信息年龄(PAoI)性能,并在源节点的传输队列中进行了分组管理和不进行分组管理。分析表明使用包管理可以获得潜在的性能收益。
We consider a system consisting of a source-destination communication link. At the transmitter of the source there is a buffer that stores packets containing status information. These randomly generated packets should keep the destination timely updated and they can be discarded to avoid wasting network resources for the transmission of stale information. In this setup, we provide an analysis of the age of information (AoI) and peak age of information (PAoI) performance of the system, with and without packet management at the transmission queue of the source node. The analysis indicates the potential performance gains obtained with the use of packet management.
