Real time status updating: Multiple sources
We examine multiple independent sources providing status updates to a monitor through a first come first served M/M/1 queue. We formulate a status age timeliness metric and find the region of feasible average status ages for a pair of updating sources. In the presence of interfering traffic with a given offered load, we show the existence of an optimal rate at which a source should generate its updates.
