Analysis of Age-Aware Slotted ALOHA
2020 IEEE Globecom Workshops (GC Wkshps, 2020 We present a steady-state analysis of threshold-ALOHA, a distributed age-aware modification of slotted ALOHA. Under threshold-ALOHA, each source remains passive until a certain age threshold $\Gamma$ is reached. Nodes whose ages exceed the threshold attempt transmission with a fixed probability $\tau$ in each slot.

The Age-of-Information Distribution in Slotted ALOHA
IEEE AccessAge-of-Information (AoI) is a new performance metric for critical networked cyber-physical systems (CPS), where performance depends on how quickly fresh data is received in update packets.

Shifted Coded Slotted ALOHA [PDF]
2018 International Symposium on Information Theory and Its Applications (ISITA), 2018 The random access scheme is a fundamental scenario in which users transmit through a shared channel and cannot coordinate each other. In recent years, successive interference cancellation (SIC) was introduced into the random access scheme. It is possible to decode transmitted packets using collided packets by the SIC. The coded slotted ALOHA (CSA) is a

Asymptotic Stability Region of Slotted Aloha [PDF]
IEEE Transactions on Information Theory, 2012 We analyze the stability of standard, buffered, slotted-Aloha systems. Specifically, we consider a set of $N$ users, each equipped with an infinite buffer. Packets arrive into user $i$'s buffer according to some stationary ergodic Markovian process of intensity $λ_i$.

Slotted Aloha for networked base stations [PDF]
2014 IEEE International Conference on Communications Workshops (ICC), 2014 We study multiple base station, multi-access systems in which the user-base station adjacency is induced by geographical proximity. At each slot, each user transmits (is active) with a certain probability, independently of other users, and is heard by all base stations within the distance $r$.

Throughput‐delay tradeoff for opportunistic spectrum access in cognitive radio networks
IET Communications, Volume 17, Issue 18, Page 2053-2067, November 2023., 2023 The authors address the tradeoff between the throughput of cognitive radio network and the delay of secondary user (SU) under a reactive channel handoff based opportunistic spectrum access scenario. The handoff blocking‐then‐reaccess scheme is deeply analyzed.
