Diffusion-based molecular communication concentration and capacity dependencies on human body temperature variation

In this paper, the effects of the variations in human body temperature on molecular communication systems that are diffusion-based are presented. In particular, we address this concern with respect to two functions, the molecular concentration at some displacement from the transmitter, and the information theoretic capacity of the system. Numerical results are provided to accentuate the temperature effect analysis. Results show that while concentration (which is more obvious at the peaks) decreased with increase in temperature, theoretic capacity increases with temperature at 50-450 μm for receiver radius of 5 μm.
