Title:
Design and Analysis of Communication Systems Using Diffusion-Based Molecular Communication Among Synthetic Bacteria

Abstract:
The design of biological networks using bacteria as the basic elements is initially motivated by a phenomenon called quorum sensing. In this phenomenon, the bacteria estimate the bacterial density in the environment by producing and sensing specific types of signaling molecules. Due to the randomness in the individual behavior of each bacterium, reliable communication between two bacteria is almost impossible. Therefore, we have proposed that a population of bacteria in a cluster is considered as a node in the network capable of molecular transmission and reception. This proposition enables us to form a reliable node out of many unreliable bacteria.

In order to study such networks, one fundamental step is to study the functionality of bacteria-population transmitter and receiver nodes as well as the diffusion channel that is used between the two nodes. The maximum achievable rate of communication between two nodes in the network, signaling schemes and reliability are among the problems of interest.
