Probability-based Data Reception in AoI-sensitive Wireless Networks

This paper considers a downlink cellular network in which a base station (BS) transmits multi-type data to a user. In this network, we analyze the weighted sum age of information (AoI) violation probability and develop a probability-based receiving data determination (PRD) policy that stochastically selects one of the data types. We then express an optimal receiving data probability and obtain the closed-form expression of that in the special case. Finally, we show that the proposed policy always outperforms the baseline schemes.
