Abstract (Summary of the Work)

The newly adopted IEEE 802.11n protocol has the scope of providing a much higher data rate, around 600 Mbps, with respect to the previous counterparts such as IEEE 802.11a/b/g. To provide this high speed, the IEEE 802.11n protocol has to adopt some key concepts like frame aggregation and channel bonding. In this work, we have developed an analytical framework to control the rate an individual user should aggregate frames in the presence of some important factors like partially overlapping channel, channel bonding, varying bit error rate over time, and bandwidth variation. The frame aggregation rate is chosen such that the throughput becomes maximum. We have considered two different frame aggregation techniques namely MAC Protocol Data Unit Aggregation (A-MPDU) and MAC Server Data Units Aggregation (A-MSDU). After showing when a user should use which frame aggregation scheme under partially overlapping channel condition, the effect of channel bonding is shown. A greedy algorithm is proposed that suggests which APs should be given the opportunity for channel bonding in order to increase the throughput. Then the results are validated by simulating the conditions assumed in the analytical model.
