Video streaming over wireless DCCP

It is envisioned that access networks will be mostly wireless in the future. Hence, it is of interest to consider extensions of the Datagram Congestion Control Protocol (DCCP) for wireless networks. This paper focuses on the problems of video streaming over DCCP in the wireless domain and proposes a cross-layer solution in which the wireless packet loss information available in the Medium Access (MAC) layer is utilized by DCCP to distinguish congestion losses from wireless losses and behave accordingly. Tests performed with our modified DCCP confirm that using cross-layer loss information prevents unnecessary rate decreases and results in better video streaming experiences.
