Dual Ionic Transport Using Calcium and Sodium Signalling for Molecular
Communication Systems
Abstract
Astrocytes have the ability to modulate neuronal communication by
regulating various levels of ionic concentrations. The development of
models for molecular communication ought to investigate the utilisation
of various ionic transportation mechanisms, with the aim of enhancing
performance and biocompatibility, thereby facilitating co-existence
within cellular tissues. In this study, we suggest the utilisation of
both Ca$^{2+}$ and Na$^{+}$ ions to investigate the
non-linearities of propagation in cellular tissues for MC. In this
study, we also investigated the impact of various ionic transport
mechanisms, including the sodium-calcium exchanger, sodium-potassium
pump, and calcium pump, to assess their impact on the intracellular
propagation of Ca$^{2+}$. We analysed four metrics, namely
channel capacity, bit error rate (BER), communication gain, and
signal-to-noise ratio, to evaluate the effects of these structures.
