Description
Summary:In order to improve the throughput under delay limits for different applications in WLAN, A-MSDU and A-MPDU aggregation in IEEE 802.11n was analyzed, and a new physical layer super-frame technology was put forward to further improve the performance. In noisy channel, the distributed coordination function (DCF) saturation throughput was derived and the impact of frame length on the throughput was discussed. Based on all these analysis, an algorithm of adaptive frame aggregation was proposed. The results show that on the condition of delay limits, there exists an optimal aggregation method to achieve maximum system throughput under a certain bit error rate (BER). Compared to the fixed frame, the proposed algorithm can effectively improve the throughput.
