This paper presents a multi-carrier molecular communication model for astrocyte tissues. The model considers molecular diversity and analyses channel path loss and capacity for molecular communication based on the concentration of Inositol Triphosphate (IP 3 ) and calcium (Ca 2+ ) molecules. Without loss of generality, we investigate the spatiotemporal concentration of these molecules and how both intracellular and intercellular signaling dictates signal propagation inside astrocytes tissues. Astrocytes are the most abundant glial cell type in the adult brain and play essential roles in brain function, such as modulating neuronal excitation, inhibition, and synaptic transmission. Results show that using combined these two molecules reduces path loss, improves data propagation, and can be an alternative for data encoding and transmission. The multi-carrier molecular communication using IP 3 and Ca 2+ has overall superior performance, showing the potential benefits of molecular diversity. |
