Re #16.

The most of the known simulation examples are using "old trace format", AFAIK.

How to change to "new trace format" : I don't know.
You can try asking here https://groups.google.com/forum/?fro...forum/ns-users

Google, ns2 change old to new trace format ...

Event, Abbreviation, Type, Value.

Looks like "Value" is self explanatory. Please study the entries.

Sumo +ns2
 

Hello sir,

I have taken different trace with different speed.
but when check the result (packet delivery ratio) getting same value for both speed(60 &120)
why?

Re #22.

Vehicle speed change or difference will have no influence on the transmission of packets.

hi sir :
i wante to ask you ho to calculate the nember of paket send and reseive from an old version of trace file in ns2
i do it like this :
if $1="s" pket_send++;
and about the packet reseive
if $1="r" pket_res++;
ther is any other condition necessary for this.
because i did'nt have a good result
thank you.
