Abstract-We consider the system where a source randomly generates status update messages and transmits them via a network cloud to the intended destination. These update message can take different times to traverse the network, which we model as exponential service times, and may result in packets reaching the destination out of order, rendering some of the earlier transmissions obsolete. We analyze the status update age for such a system, and show that it tracks well with simulation results.
Kam et al. REF investigated the average AoI of a more complex scenario, where the generated status updates may arrive at the destination out-of-order and the outdated status updates are obsolete.
