  In this work the estimation of the lateral distribution function in Extensive
Air showers was performed by using a system for air shower simulations which is
called AIRES version 2.6 for different hadronic models like (QGSJET99, SIBYLL
and SIBYLL1.6). The simulation was fulfilled in the high energy range
(10^15-10^19 eV) for different primary particles like (gamma, protons and iron
nuclei) for vertical showers. This simulation can be used to reconstruct the
type and energy of the particle that generated Extensive Air showers for
charged particles that registered with different arrays.
