ABSTRACT
The IEEE 802.11n protocol, ratified on September 2009, promises both higher data rates up to 600 Mbit/s and further range. In this paper we investigate the effect of most of the proposed 802.11n MAC and physical layer enhancements on the adhoc networks performance. Experimental results in a real indoor wireless testbed demonstrated the effectiveness of 802.11n enhancement. The channel bonding feature has the most significant impact on the throughput. The aggregation mechanism is not always effective. Then, we propose a new frame aggregation scheduler that considers specific QoS requirements for multimedia applications.
