Biological communication networks: A first step in modeling and analysis
We review how biological systems undertake signaling specifically examining, signal transduction and signaling via electrons and molecules. Key processes will be reviewed and important mathematical abstractions provided. With essential building blocks in place, several biological communication systems will be investigated including different modulation methods, associated demodulation strategies and network frameworks. Two illustrative biological networks based on bacterial populations will be examined: electron transfer in bacterial filaments (multi-hopped bacterial networks) and the inducement of quorum sensing in homogeneous populations (multi-terminal bacterial networks). Queues are shown to be a simple, yet powerful method by which such systems can be modeled. Our initial models provide excellent match with experimental data. While the diffusion of chemical signals in the surrounding medium of biological systems has been heavily studied, the role of such processes is not fully understood in certain bacterial interactions. Our queuing models further suggest biologically relevant channel models for information theoretic analysis of larger systems. Our studies are motivated by the fact that microbial communities play a significant role in bioremediation, plant growth promotion, human and animal digestion, disease, elemental cycles, the carbon-cycle and maintaining clean water.
