[Nfd-dev] Interest scoping and broadcast channels

[Burke, Jeff]

Hi folks,

Can you please suggest how to handle the following use case:

Consider a low-power device communicating on a broadcast channel.   If we want the device to "hear" Data in a given prefix that is transmitted on the broadcast channel but not itself transmit an interest for it, how can we do that?   Put another way, will/can a locally-scoped interest be matched against Data packets arriving on a non-local Face?

More on the use case:

On a low-power sensor node we want to delay responding to a general prefix if another node has already responded.  We can introduce (for example) a random delay and then check if some other node has answered; the most NDN-like way to check seems to be to have an outstanding Interest for the prefix locally that is compared with Data coming in over the broadcast media.

Thanks,
Jeff
