The Media Access Control (MAC) introduced in the IEEE802.11n reduces the bottleneck in the legacy IEEE802.11 using different techniques such as frame aggregation and block acknowledgments. In this paper, the authors investigate the interaction between MAC frame aggregation and Transmission Control Protocol (TCP). MAC layer interaction with TCP is very important as TCP determines the end-to-end transfer rate. Regarding the interaction with TCP a comparison is made through simulations among different TCP congestion control techniques, like Reno, NewReno, Vegas, Tahoe and Selective ACKnowledgments (SACK).
