Abstract
As average packet sizes in wireless networks shrink and data

rates increase, the fundamental CSMA mechanism in the

802.11 protocol family is put under stress. With the emerg-

ing 802.11ax standard, the carrier sensing mechanism is low-

ering the efficiency of the protocol to the level of random

access (ALOHA), and as future-generation 802.11 standards

emerge, CSMA-based protocols will fall below this level. In

this paper we make two main contributions to the litera-

ture. First, we will extend previous analysis to examine

more closely the quality of the information obtained from

channel sensing, in particular the probability of this infor-

analysis to improve existing CSMA-based protocols, in par-

ticular the 802.11 protocol family. (Less)
