IEEE 802.11n standard has introduced the new schemes in MAC and PHY layers to improve network throughput. Frame aggregation and Block ACK are mainly defined to increase the efficiency of the MAC layer. There exists still problem in IEEE 802.11n. When block ACK request and/or response frames are missing or received in error, the sender does not know the status (success/failure) of each frame in the aggregated large frame and retransmits all the frames. This can cause a lower network performance. To solve this problem, we propose a new effective scheme, called reduced retransmission of MPDUs (RRM) scheme. In the proposed scheme, when a sender does not receive a block ACK response frame, it just transmits a next data frame and requests a block ACK. Therefore, it can retransmits the erroneous frames. Performance of the proposed scheme is investigated by simulation. Our results show that the proposed scheme is very effective and improves the performance under a wide range of channel error conditions.

“…The overhead consists of backoff process, DIFS, MAC header, ACK, SIFS and PHY header. Some research have been propose different schemes to increase the throughput efficiency of MAC layer; among which are Burst ACK (Wu et al, 2013), Block ACK (Arif and Sari, 2012), Concatenation Packet (Hong and Tsai, 2010), Aggregation (Charfi et al, 2012) and AFR (Li et al, 2009).…”

Aggregation with Fragment Retransmission (AFR) is a scheme designed for frame transmission to increase efficiency at the MAC layer throughput. AFR provides a higher throughput compare to Distributed Coordination Function (DCF) scheme. However AFR scheme did not has QoS service function when compared to DCF scheme. DCF scheme already has contention-based QoS service using Enhanced Distributed Coordination Function (EDCA) scheme. In this study, we enhanced the AFR scheme in order to provide the QoS function and called it as AFR plus QoS or abbreviated as AFR+Q. We developed the analytical model to investigate the saturation throughput of AFR+Q scheme. We designed the Markov chain model as state transition of the backoff counter from each Access Category (AC) and we derived the mathematical model of the transmission probability and the saturation throughput of each AC. The simulation result using Matlab shown that the AFR+Q scheme provide higher saturation throughput compared to EDCA scheme. The higher throughput in AFR+Q scheme is produced by the better transmission probability, employed packet fragmentation and aggregate frame schemes.

“…Gao et al [5] Analyzed the throughput performance of the M-group IEEE 802.11 DCF heterogeneous networks with a distinct input rate, number of nodes and initial backoff window size in each group. Arif et al [6] analyze the throughput of EDCA scheme using A-MSDU and Block ACK. However no one has analyzed the effect of anomalous slot to the throughput of DCF and EDCA schemes.…”

In DCF and EDCA schemes, the number of collisions increased caused the number of anomalous slots also increased. These conditions caused the average duration of collision will be much longer and result in a decreased network throughput. In this paper we have proposed SASA scheme to avoid anomalous slot after the collision. Simulation results show SASA scheme produces higher throughput compare to DCF and EDCA schemes.
