Résumé
With the advent of low-cost WLAN devices, the delivery of multimedia content is highly desirable. Such applications require high throughput and near-real time for quality viewing. The use of next-generation WLAN 802.11n and physical layer multicast transmission for a wide range of wireless terminals introduces many significant challenges. The impetus of the present study is to describe a cross-layer approach, enabling techniques as beamforming, MIMO antennas, OFDM and low latency MAC operation. Our simulation results show a substantial improvement in network performance for our proposed strategies in IEEE802.11n wireless access networks. ©2008 IEEE.
