Information and Communication Technology (ICT) has been facing a challenge to quantum limits of semiconductor technology. Since the speech by Nobel laureate Richard Feynman, it is widely believed that quantum and molecular approaches may replace part of the future needs of semiconductor technology. Molecular communications, which achieves information exchange by the transportation of molecules, is emerging as an alternative with underestimated potential, particularly in massive communications and the molecular biological phenomenon (e.g., intercellular signaling and intracellular gene networks). Figure 1a shows a model of end-to-end point-to-point molecular communications, while molecular communications tends to function on a large scale and thus large networks. The need to fully understand molecular communications is twofold.
