I wanted to design a protocol which is based on AODV. although my question is 
not related to NS. maybe someone can help me.I noticed that AODV uses the 
combination of broadcast ID and source address to drop repeated request 
packets.  although the request packet has another field in its header which is 
source seq. no.can AODV use the combination of source seq. no. and source 
address for dropping repeated packets?is it possible that two different request
 packets (ie. different broadcast ID) from the same source have the same source 
sequence number?
thanks in advance
