Cross Layer (Application and Medium Access Control) Design and Optimization of Wireless Network for Real Time Video Transmission

Provided by: International Journal of Scientific and Research Publication (IJSRP) Topic: Enterprise Software Format: PDF
Robust streaming of video over 802.11 WLANs (Wireless Local Area Networks) poses many challenges, including packets losses caused by network buffer overflow or link erasures, time-varying wireless channel and video content characteristics etc. To improve the performance of real-time video transmission over 802.11 WLANs, the use of cross layer design approach is required which allows communication between layers by permitting one layer to access the data of another layer, thereby facilitating the exchange of information. One of such design approach includes APPlication (APP) and Medium Access Control (MAC) layers considerations and is explored in this paper.
