Channel Capacity Analysis of Blood Capillary-Based Molecular Communication

摘要

Molecular communication (MC) is a promising bio-inspired communication method in future nano-networks. Diffusion-based channel is the most basic yet active branch of the MC. This paper introduces a new bio-phenomenon into MC, namely, blood capillary. While most work on diffusion-based channel focus on molecules concentration and described by Fick's law, this paper proposes to use Langevin equation in microcosmic aspect. In this paper, the model of blood capillary system also considers the vesicle release process, and vesicle propagation process. With the modeling of the integrated blood capillary system, this paper analyzes channel capacity for the system.
