 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.
