not sure what publications or what definition of "recent" you are
using - i've seen self organisign hierarchies (not just spine) based
ad hoc protocols which do way way better....depends on the _mobility_
model - a lot of people have naive mobility models - if you use a mix
of techniques, and a mix orf appropriate scale mobile/wireless node
velocity models, you can do really quite well...

esp. if you dont start with ip:-)

 cheers
