Dario,

TCP (in all of its versions) has well
known flaws when employed
in wireless environment, which is
usually characterized by high
error 
rates.
This is due to the way TCP
reacts to packet losses, which
it 
assumes due to congestion
and not medium unreliability.

Thus, there is 
no particolar
version of TCP which is more
suitable for wireless 
networks,
unless you
 - consider some ad-hoc
   modifications which 
have
   been proposed by several
   researchers, but which
   are not 
standard and probably
   not implemented in ns-2.
 - use an error free 
channel,
   which is not realistic, but
   makes TCP works a lot 
better.

Regards,

Marco Fiore

wireless simulation


Hi,

can someone suggest me 
which Agent Tcp is
the more suitable for wireless
simulation?

Thanks.
