Enhanced Two-Level Frame Aggregation with Optimized Aggregation Level for IEEE 802.11n WLANs

IEEE 802.11n defines a significant two-level frame aggregation scheme aimed at improving the transmission efficiency of MAC layer. However, the performance of the two-level frame aggregation scheme does not meet the user expectation due to the inevitable aggregation and retransmission overheads. To overcome this problem, an enhanced two-level frame aggregation with the optimized aggregation level is proposed in this letter for IEEE 802.11n...
