Abstract
Nowadays, 802.11 standard increasingly plays an important role in daily life as well as in the industry by various applications and advantages such as low cost , quick deployment, flexible configuration, user mobility support, etc. Along with evolutions of this standards from 802.11 b, g, n to ac main difference is in the modulation method and improvement at PHY layer, medium access control mechanisms almost not change except HCF which is an optional mechanism for delay-sensitive applications. An evolution in medium access control mechanisms is needed for higher performance 802.11 standard when the improvements at PHY layer are more close to theoretical limitation. This chapter detailed the characteristics of DCF and PCF—two important channel access mechanisms in IEEE 802.11 . Overview about 802.11 MAC is introduced first followed by PCF and DCF mechanism. This chapter presented comparisons between DCF and PCF in two simulation scenarios.
