Network Coding (NC) techniques for lossy wireless networks have been used for fault-tolerant and timely delivery of streaming video data. Recent research on inter-session NC notwithstanding, reliable transmission of high quality media over wireless networks continues to be a challenge. The effects of traffic and network dynamics on coding block size and thereby on latency added at playback were studied, and the interaction of congestion control on the coding technique to remedy this were examined. Simulations show an inherent latency in video playback when TCP with random linear NC is employed as the receiver needs to wait for a certain number of packets to arrive before they are decoded.
