We investigate the phenomenon of integer quantum Hall effect in a square
lattice, subjected to a perpendicular magnetic field, through
Landauer-B\"uttiker formalism within the tight-binding framework. The
oscillating nature of longitudinal resistance and near complete suppression of
momentum relaxation processes are examined by studying the flow of charge
current using Landauer-Keldysh prescription. Our analysis for the lattice model
corroborates the finding obtained in the continuum model and provides a simple
physical understanding.
