Hello everybody
I have a problem that makes some days I am blocks.
I achieved several scripts of mobility in order to draw the curve: number of
packets received / number of packets gave out according to the mobility.
I generated several scripts with. / setdest,with variable M between 10 and 100.
I notice that the number of packets received / number of packets didn't give
out changes
I give you my script tcl
s1:file of scenario
f1:file of trafic exchange
and we use 10 scenario (M=10,M=20.....M=100)
Please help
