A MAC Performance of Mobile Ad-hoc 802.11ac LAN Over Correlated Fading Channel

Author(s) : HA CHEOL LEE


FER (Frame Error Rate) and MAC (Medium Access Control) throughput are derived over error-prone channel in the IEEE 802.11ac mobile ad-hoc LAN. In this paper, DCF (Distributed Coordination Function) protocol and A-MPDU (MAC Protocol Data Unit Aggregation) scheme are used to evaluate the MAC throughput. Using theoretical analysis method, A MAC saturation throughput is evaluated according to the mobile speed and the number of frames in each A-MPDU on the condition that the number of station, frame payload size, transmission probability, the number of parallel beams and fading margin are variables. When the mobile speed is typically 1 m/sec and the number of aggregated MPDUs in each A-MPDU is 100, it is identified that the MAC layer throughput of IEEE 802.11ac can be maximally attained up to a 97.2% of physical transmission rate in this evaluation.
