Sammanfattning

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-
mation being incorrect and the correlation between true and
sensed channel state. Second, we examine how to use this
analysis to improve existing CSMA-based protocols, in par-
ticular the 802.11 protocol family.
