@zhuoshuguo I think your example is a classical case of over-complicating the situation. For a MAC protocol this might be something to consider, but just as a measure of keeping duplicated packets at bay this sounds like overkill to considering (or if a wrong packet get's accidentally in dropped in a corner-case: so what, upper layers may resend). Also: since @gebart is proposing to add this to the `recv` of the IEEE 802.15.4 glue-code to GNRC, you also still can add a timing-based implementation for a MAC protocol.
