Analysis of Connectivity in Diffusion-Based Molecular Nano Communication Networks

ABSTRACT: A nanonetwork is an interconnection of nano devices that are made up of nano-scale components. Several approaches for designing and implementing nanonetworks have been presented in recent years. Diffusion-based molecular communication is one of these approaches that use molecules as means of transmitting information in network. In diffusion-based molecular communication, molecules or particles diffuse in an aqueous environment under Fick’s laws of diffusion to move from transmitter to receiver. In order to have full cooperation among nano devices, there must exist a communication path between every communicating pair. Hence, the primary aim of this study is to employ methods used for analyzing random networks to evaluate connectivity properties of nanonetworks that employ diffusion-based molecular communication techniques. Extensive simulations have been performed to investigate the effects of varying node density, number of particles released per node, and concentration threshold for detection at the nodes. The corresponding results in two and three-dimensional environments have been presented. Keywords: Connectivity, diffusion, molecular communication, nanonetwork. ……………………………………………………………………………………………………………………………………………………………………………………………………………………
