Analysis of a Propagation Model for Molecular Communication in Nanonetworks

ABSTRACT: Nano-communication is a new technological invention that is achieved by the use of nanomachines with nanoscale functional components, with extremely limited workspaces. It provides numerous new solutions in the fields of biomedical sciences, industry, and the military by enabling communication among nano-devices in a scale ranging from one to a hundred nanometers. Single nanomachines are able to collaborate with each other through communication and two primary methods for communication among the nano-devices are based on molecular communication or electromagnetic communication. The former uses molecules instead of electromagnetic waves and involves some important processes – encoding, transmission, propagation, reception, and decoding. One significant subject in molecular communication is to analyze how molecules propagate through a fluid medium. In this thesis; we propose a new analytical model for the propagation process of molecules based on the random walk mechanism by formulating the probability density of latency in blood and water. The proposed model takes into account crucial parameters such as the radius of the propagating molecules, viscosity, drift velocity, and the temperature of the fluid medium with respect to different shear rates and thereupon can be used as a general propagation model for nano-communication. The main aim of this thesis is to determine the probability density of latency for the propagating molecules in blood and water that show different viscosity values in different temperatures. Based on the simulation results, latency is highly affected by the distance between source and destination, temperature, shear rate, viscosity, and radius of the propagating molecules through the blood medium. We also evaluate the probability density function (PDF) of latency for different temperatures with different nanomachine distances through the water medium.
