Thanks for the update. My concern wasn't that the draft lacks
implementation details. It is that I think this type of result is
better published in a journal or presented at a conference. It is a
solution that works well for one particular model of a wireless
channel, but wireless channels are very hard to model accurately.
If you want this protocol standardized by the IETF, I would recommend
publishing several papers evaluating it under a wide range of wireless
settings (WiFi, 3G, LTE, WiMax, satellite, Zigbee) and showing that
the algorithm is robust. Then summarize the results in a
recommendation to the IETF.
