Optimal Dynamic Frame-Slotted Aloha : (ODFSA)
, 2011 Passive UHF RFID systems using Dynamic Frame-Slotted ALOHA (DFSA) adjust the frame size according to the number of tags, but frame size N is equals to 2^Q and cannot be adjusted exactly to the number of tags to be identified. In this paper, we propose an

Comparing Delay-Constrained ALOHA and CSMA: A Learning-Based Low-Complexity Approximate Approach
IEEE Open Journal of the Communications Society, 2021 Supporting delay-constrained traffic becomes more and more critical in multimedia communication systems, tactile Internet, networked control systems, and cyber-physical systems, etc. In delay-constrained traffic, each packet has a hard deadline.

IET Networks, Volume 14, Issue 1, January/December 2025.This paper investigates the characteristics of slotted ALOHA and PD‐NOMA hybrid schemes. The results of this paper reveal that achieving a balance between fairness and performance improvement may be inherently challenging in grant‐free access schemes. ABSTRACT This paper investigates the characteristics of slotted ALOHA and power‐domain nonorthogonal ...
