Abstract:The famous binary backoff algorithm in IEEE 802.11 MAC layer can forget the contention level between each successfully transmitted data frame and hence suffers significant performance degradation when the contention level is high. In IEEE 802.11 standard, a distributed contention control (DCC) algorithm is proposed to address this problem by observing how many of slots in the last backoff period were busy, i.e. slot utilization. The introduction of slot utilization can provide good estimation of the most recen… Show more
