Game-Based Channel Access for AoI-Oriented Data Transmission Under Dynamic Attack
IEEE Internet of Things Journal, 2022Efficient grant-free uplink transmission is critical in minimizing Age of Information (AoI) in multichannel Internet of Things (IoT) networks. But less attention has been paid to this topic especially when dynamic channel access attacks (DCAAs) exist. To

Channel configuration of multiple-access channel
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004This paper investigates the channel configuration of multiple-access channel (MAC) by decomposing the MAC into finite subMAC and also proves that there exists an input probability that achieves boundary of a capacity region and the total capacity of the original MAC.

Channel-hopping multiple access
2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2000The medium-access control (MAC) protocols for wireless networks proposed or implemented to date based on collision-avoidance handshakes between the sender and receiver either require carrier sensing or the assignment of unique codes to nodes to ensure that intended receivers hear data packets without interference from hidden sources.

Cognitive access algorithms for multiple access channels
2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013This paper considers a multiple access fading channel where each terminal has a different belief about the channel states and adapts its transmission policy to the belief. In this setting, frequency division multiple access (FDMA) and channel aware random access (RA) are two special cases.
