  In this paper, we propose an end-to-end channel model for molecular
communication systems with metal-oxide sensors. In particular, we focus on the
recently developed table top molecular communication platform. The system is
separated into two parts: the propagation and the sensor detection. There is
derived, based on this, a more realistic end-to-end channel model. However,
since some of the coefficients in the derived models are unknown, we collect a
great deal of experimental data to estimate these coefficients and evaluate how
they change with respect to the different system parameters. Finally, a noise
model is derived for the system to complete an end-to-end system model for the
tabletop platform.
