Network coding aware routing protocols have been an interesting research topic in recent years. In this paper, the authors explore similar routing gains with physical layer coding techniques. A source routing protocol S3 is proposed to be implemented with a routing metric called iETT. By extending the traditional ETT measurement, iETT provides a simple way to make the routing protocol interference-aware. To further enable superposition coding and successive interference cancellation, S3 uses iETT to explore physical layer coding opportunities and measure potential gains in network throughput.
