This paper proposes using the uncertainty of information, measured by Shannon's entropy, as a metric for information freshness. The system considered in the paper involves a central monitor observing multiple binary Markov processes through multiple communication channels.
This paper proposes using the uncertainty of information (UoI), measured by Shannon's entropy, as a metric for information freshness. We consider a system in which a central monitor observes M binary Markov processes through m communication channels (m
