Analysis of Access Delay and Delay Jitter for the CSMA/CA Mechanism with Inactive Period [PDF]
Radioengineering, 2019 Owing to the distributed features and flexibility, carrier sense multiple access with collision avoidance (CSMA/CA) mechanisms have been widely adopted in wireless networks. Considering energy consumption, we devote to explore an energy efficient carrier

CSMA versus prioritized CSMA for air-traffic-control improvement [PDF]
Proceedings, IEEE Aerospace Conference, 2003 OPNET version 7.0 simulations are presented involving an important application of the aeronautical telecommunications network (ATN), controller pilot data link communications (CPDLC) over the VHF data link mode 2 (VDL-2). Communication is modeled for essentially all incoming and outgoing nonstop air-traffic for just three United States cities ...

On selfish behavior in CSMA/CA networks [PDF]
Proceedings IEEE 24th Annual Joint Conference of the IEEE Computer and Communications Societies., 2005 CSMA/CA protocols rely on the random deferment of packet transmissions. Like most other protocols, CSMA/CA was designed with the assumption that the nodes would play by the rules. This can be dangerous, since the nodes themselves control their random deferment.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This paper introduces a stochastic geometry‐based analytical framework to evaluate and enhance communication reliability and road safety in connected autonomous vehicles (CAVs). By modeling roads using Poisson Line Processes and vehicle distributions with Poisson Point Processes, the framework enables accurate assessment of key performance metrics like

Evaluation of Mechanisms for Reliability and Awareness in Platooning Under Low Transmit Power
IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.Low transmit power, whether due to transmit power control or deliberate settings to reduce interference, improve coexistence or save energy, can undermine the awareness range and beacon reliability needed for safe platooning. This paper evaluates reliability mechanisms and finds that no single mechanism works at very low power without trade‐offs ...
