Optimal Sampling and Scheduling for Timely Status Updates in Multi-source Networks
IEEE Transactions on Information Theory(2021)
摘要
We consider a joint sampling and scheduling problem for optimizing data freshness in multi-source systems. Data freshness is measured by a non-decreasing penalty function of age of information, where all sources have the same age-penalty function. Sources take turns to generate update packets, and forward them to their destinations one-by-one through a shared channel with random delay. There is a ...
