Summary
This chapter characterizes the average Age of Information (AoI) for the case of having multiple sources sharing a service facility with a single server. In particular, a simplified explanation of the SHS for AoI approach is provided to calculate the average age of updates of any source at the monitor. This approach is applied to various queueing systems including FCFS, M/M/1*, and M/M/1/2*, and the latter two with and without source priorities.
