Abstract
We characterize the Price of Anarchy (PoA) in a single channel under the presence of K competing
sources. As performance metric we consider the Age of Information, which measures the freshness
of information in a remote system. In our main results we show that when the service times of all
sources are equal the PoA is 2 − 1
K , and that otherwise the PoA is unbounded from above. Numerical
computations show that the PoA increases with the disparity of the service rates
