Channel modelling of molecular communications across blood vessels and nerves

Nervous cells and blood vessels form crucial circulating networks in human body. They are interdependent on biological level and communicate with each other via abundant interaction phenomena. These interactions are complex while worthy concerned, which may guide to implement controllable relaying communication across nervous and blood vascular heterogeneous channels. In this paper, we highlight the heterogeneous theme in area of molecular communication. We set up a basic framework based on the heterogeneous network interactions, in which two properties are proposed to make those interactions easier understood on communication level. Moreover, we establish a one-way single-threaded channel model as a case study based on the network framework, and give the mutual information expressions. We aim to explore the possibility of effective communication. The results show that settings of the adjustable system have a significant impact on the relaying performance, as well as the mutual information.
