Abstract :
A number of service differentiation mechanisms have been proposed for, in general, CSMA-CA systems, and, in particular, the 802.11 enhanced distributed coordination function. An effective way to provide prioritized service support is to use different inter frame spaces (IFS) for stations belonging to different priority classes. This paper proposes a novel analytical approach to evaluate throughput and delay performance of IFS based priority mechanisms.
