From what I understand, OLSR has a better mechanism for maintaining
the "mesh information." If you recall any change in mesh was
previously broadcasted to all listeners. OLSR is configurable. For
instance, information would only be broadcasted to two levels of one
devices immediate neighbor not the whole mesh cloud. Another issue we
had was maintaining mesh information in a limited memory space on the
WLAN module; OLSR would now process that information.
