Store and Forward

[decanus]

As part of our improvements to whisper in vac, we have created MVDS a ARQ protocol and remote log, a standardized method for storing messages on remote servers.

However these 2 protocols do not interact, so the improvements we get from the remote-log itself are rather moderate. We need some kind of store-and-forward model using these 2 protocols in order to ensure that we get the most out of both. Giving offline nodes the ability to no longer retransmission messages locally while ensuring a message will be delivered.

The goal of this issue is to do research on how this can be done and later summarize it into a post on our forum, or create a spec out of it.

Questions

• How can we ensure a node that has stored a message continues forwarding the message to the recipient?

Literature

• Babel Routing Protocol - rfc
• A Secure Incentive Scheme for Vehicular Delay Tolerant Networks Using Cryptocurrency - paper
  Although not exactly about store and forward, the insights in a paper on the incentives for delay tolerant networks could be resourceful.

It might make sense to look at active replication here too, thanks for the pointer @oskarth.
