Information transmission based on network coding over wireless networks: a survey

Network coding (NC) for wireless local area network has received a lot of attention from researchers. It replaces the traditional methods of video erasure protection. The principal of NC is to combine several packets together before their transmission. Thus, NC is able to provide higher throughput, reliability and efficient transmission. Up to now, many works have been done to ensure the advantages and the robustness of NC against the packet loss and link failures. The performance gains of NC are successfully processed not only for data to increase throughput, but also for video streaming over wireless networks. In this context, this paper surveys and discusses the most popular approaches based on NC of both data and video transmission over wireless network (static or dynamic). Strength and limitations for robust video streaming and data transmission are deeply discussed.
