We consider a content-caching system thatis shared by a number of proxies. The cache could belocated in an edge-cloud datacenter and the proxies couldeach serve a large population…
The distribution of age-of-information performance measures for message processing systems
George Kesidis, Takis Konstantopoulos, Michael Zazanis
The idea behind the recently introduced "age of information" performance measure of a networked message processing system is that it indicates our knowledge regarding the "freshnes…
Relative Age of Information: Maintaining Freshness while Considering the Most Recently Generated Information
George Kesidis, Takis Konstantopoulos, Michael Zazanis
A queueing system handling a sequence of message arrivals is considered where each message obsoletes all previous messages. The objective is to assess the freshness of the latest m…
