I do not like ietf manet protocols. Infact a lot of people like them, perhaps because there is an already working implementation and so they can use them. But infact there are better alternatives: http://www.wikipedia.org/wiki/Ad_hoc_protocol_list and also http://www.ica1www.epfl.ch/TNRouting > The only mesh routing protocol that seems to > have a chance of scaling up to internet size is geographic routing.
