In this paper, we focus on the Peak Age-of-information (PAoI) performance in Carrier Sense Multiple Access (CSMA) networks. Specifically, by assuming that sensors are equipped with unit-size buffers and the Bernoulli update process, the PAoI expression and the optimal access probability for minimizing PAoI are derived. A comparison between the optimal PAoI in CSMA and that in Aloha is presented, identifying the age performance in CSMA could be inferior to that in Aloha if the ratio of sensing time to packet length is high. The critical threshold in terms of this ratio is characterized, which is shown as a decreasing function of traffic arrival rate. It reveals that compared to CSMA, Aloha is a better choice in scenarios with large propagation delay and light traffic, such as low earth orbit mobile-satellite communications for Internet-of-Things services.
