Research On The Receptor Response Mechanism Of Diffusion Molecular Communication

The rapid development of nanotechnology and biotechnology has changed the daily behavior of human health and communication,and these technologies have a particularly significant role in communication.Because the size and power consumption of transceivers and other components of traditional communication technologies are no longer suitable for nano-networks,and the interconnection between nano-machines allows them to cooperate and share information,expanding the functions of a single nano-machine and promoting molecular communication and the birth of a new communication method.Molecular communication uses molecules instead of electromagnetic waves or sound waves to encode and transmit information,enabling artificially involved communications to be implemented in complex or specific environments.It has tremendous application potential in many fields such as medicine,manufacturing,and defense.This thesis introduces the basic concepts of molecular communication,comparison with traditional communication,and its current research results.In particular,it analyzes the current physical implementation of molecular communication receiving equipment and the basic reaction principle of its information molecule reception,and explains its technical difficulties,advantages and disadvantages.Biological models with different reaction mechanisms are introduced,the importance of reaction mechanism between information molecules and receptors in molecular communication is explained,and then several experimental platforms for molecular communication are briefly stated.This thesis uses the existing three-dimensional point source communication network model to analyze the communication output characteristics of the reversible binding reaction,and further analyzes the surface area impact of the receiver on the output and the concentration ratio of ligand-receptors in system.At the same time,it redesigns the molecular communication network by dividing the medium space uniformly,and analyzes the effects of different receptor reaction mechanisms on communication results in terms of positive binding rate,positive reaction rate,and biofilm.Finally,a new reaction mechanism is given,providing a reference for the analysis of subsequent network model.The work in this thesis is helpful for further research on the information molecular acceptance process in molecular communication,and provides a theoretical reference for the physical implementation of molecular communication receiving equipment.
