  We present Mathematica7 numerical simulation of the process
$pp\rightarrow\mbox{jet}+E_{T}^{miss}$ in the framework of modified
Randall-Sundrum brane-world model with one infinite and $n$ compact extra
dimension. We compare the energy missing signature with the standard model
background $pp\rightarrow \mbox{jet}+\nu \bar{\nu}$, which was simulated at
CompHep. We show that the models with numbers of compact extra dimensions
greater than 4 can be probed at the protons center-of-mass energy equal 14 TeV.
We also find that testing the brane-world models at 7 TeV on the LHC appears to
hopeless.
