Correct me if I'm wrong, the IETF doesn't have any activities looking at the fixed mesh case.
I haven't read the IEEE docs you've sent.
Could the "fixed mesh" case match something like "micro-mobility" or "local mobility"?
If you were to look into fixed meshes, how would you approach the problem definition and what tools would you use? My approach to it would be to use address autoconfiguration coupled with routing protocol exchanges. The deployment space would be rather limited, say no larger than 50 vertices for the mesh.
