Proposed herein is a complete solution to choose the appropriate PHY mode for delivering packets between nodes based on loss differentiation and sample rate. With the proper PHY mode selection, the described techniques are capable of distinguishing between fading and collision as the source of poor network performance, which can greatly assist in decreasing the latency of frames in low-power and lossy networks (LLNs).
