6-2 Cross-Layer Rate Control for Robust Video Transmission over Wireless LANs

Abstract

According to the recent progress of wireless LAN technologies, short range video transmission using a wireless LAN is getting popular. Since the throughput of wireless LAN is getting smaller when wireless condition become worse, the bit-rate of video streaming system should be changed to adapt this change. In this paper, a method to estimate available bit-rate over the wireless network using both receiver's reports and link layer information of wireless devices is introduced. Our experiment shows that the method significantly improves the robustness of video streaming system using wireless LAN.
