Abstract

In this paper, we present an analytical model for a
diffusive molecular communication (MC) system with a reversible
adsorption receiver in a fluid environment. The time-varying
spatial distribution of the information molecules under the
reversible adsorption and desorption reaction at the surface of a
bio-receiver is analytically characterized. Based on the spatial distribution,
we derive the number of newly-adsorbed information
molecules expected in any time duration. Importantly, we present
a simulation framework for the proposed model that accounts
for the diffusion and reversible reaction. Simulation results show
the accuracy of our derived expressions, and demonstrate the
positive effect of the adsorption rate and the negative effect of the
desorption rate on the net number of newly-adsorbed information
molecules expected. Moreover, our analytical results simplify to
the special case of an absorbing receiver.
