Impact of aggregation headers on aggregating small MSDUs in 802.11n WLANs

The main goal of the IEEE 802.11n standard is to achieve more than 100Mbps of throughput at the MAC service access point. This high throughput has been achieved via many enhancements in both the physical and MAC layers. A key enhancement is frame aggregation which reduces the overheads and increases...

description The main goal of the IEEE 802.11n standard is to achieve more than 100Mbps of throughput at the MAC service access point.
