Summary:As a promising enabler for sensing data collection manner, Mobile Crowdsensing (MCS) can play an important role due to its low implementation cost, flexible collection manner and controllable data quality traits. To investigate the sensing data freshness metric as well as ensure the data security, with the help of stochastic geometry tool, this paper designs a Non-Orthgonal Multiple Access (NOMA)-based Age of Information (AoI) performance analysis for privacy preservation-oriented MCS. To be specific, the privacy-preserving MCS system model is established at first. Then, based on stochastic geometry and queue theory, the AoI performance under cryptography guarantee is investigated. Next, given the traits of wireless channel and mobile terminal, mathematical AoI expressions for sensing data are determined under different serving rules, queue models and transmission schemes. Finally, under various parameter settings, numerical results evaluate the correctness and effectiveness of the established AoI model.
