Matt, I was intrigued by your throwaway "not another multi hop routing protocol" comment. As far as I can tell, the field is very slow-moving. The state of the art, Babel, is at least 5 years old and is an incremental improvement on protocols that are at least 20 years old. Some very promising research was done into DHT-based routing with Scalable Source Routing, but this work is now from more than 10 years ago, and interest seems to have dropped off completely.

Are there a bunch of protocols that I don't know about?

Are you maybe referring also to centralized path finding algorithms? This would explain the comment.




Nobody needs multihop routing protocols. Show me one instance in which they have been useful, despite 20+ years of academic work in the area.
