Video Streaming over Wireless LAN with Network Coding

Client diversity is one of the main characteristics of wireless networks. Due to channel diversity, multicasting a video stream in a wireless LAN to multiple clients with different channel conditions is a challenging task. A promising approach for such a problem is to use multiresolution video coding (i.e. scalable video coding) with network coding. In this paper, we study a triangular approach for network coding in a one-hop wireless LAN network. Previous work searches for all possible coding opportunities, which is computationally expensive. In this work, we use regression to derive efficient transmission protocols that take into account the delivery rate, as well as the variance of the channels. We show that the regression approach is more practical than the previous method. Also, the achievable rate using the regression approach can produce competitive results.
