Improved Optimal Slotted CSMA/CA Protocol
... Wang, et al. [6] has shown that when an IEEE 802.15.4 network has many nodes and is almost saturated, the probability of collision is large, and the throughput is small. Jing, Hui, and Hitoshi Aida (2011) [7] in paper ...

CSMA/CA in Time and Frequency Domains
... To quantify these two goals, we define the interference as the fraction of the total spectrum that is used by more than one station at any given time. Similarly, we define the spectrum usage as the fraction of total ...

Delay distributions of slotted ALOHA and CSMA
... Abstract—In this paper, we derive the closed-form delay distri- butions of slotted ALOHA and nonpersistent carrier sense mul- tiple access (CSMA) protocols under steady state. Three retrans- mission policies are ...
