hi ALL ,
I want to calculate the number of hops in my network
I get 3 replies from ns-users so I tried this 3 possibilities :
1)is to use $ns_ new-trace and after I use the parmaeter Pf whitch
calculate the number of hops but when i add in my script
$ns_ new-trace I get a lot of errors which I don't anderstand
2)so i searched in the the net and found thant we must declare
$ns_ use-newtrace to use the new trace format and after we must use the
parmaeter Pf whitch calculate the number of hops
but when i use $ns_ use-newtrace i don't get this "-Pf" in my trace files
???
what is the difference between $ns_ use-newtrace and $ns_ new-trace?
i found also that "-Pf" is get with cbr or tcp traffic , or in my case i
don't use any one of them ,so it is the raison that i don't get the "-Pf" in
my trace files
am I wrong ?
3) the third methode is to use the old format trace ,the 16 colon gives the
number of hops
but i don't find any document whitch talking about this methode ????
4)I found also that in new trace format for DSR AND AODV "-ph" gives number
of hops
is it write ?
I must use the 3 protocols : DSR DSDV AODV in order to compare their
performance
so please if there is any one can tell me what can I do
which method among the fourth cited ??????
Thank a ton in advance
