Molecular nanonetwork channel model

Molecules serve as information carriers in molecular communications. Information bits are encoded by varying the concentration of molecules. The information bits thus encoded are conveyed to the receiver through molecular diffusion. A ligand-receptor receiver measures the concentration of the molecules in order to retrieve the information. In this reported work, a memory channel using first-order Markov chain is developed. A methodical approach to calculate channel capacity is followed. Also, a closed form capacity equation has been derived.
