The Effect of Emerging Traffic Patterns on High Speed Wireless LANs

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

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-
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.
