Nanomachines are expected to be very simple devices, but nanonetworks, the association of nanomachines, are expected to increase their capabilities, allowing them to share information in order to perform more comp ..."
Abstract - Add to MetaCart
communication alternatives have been recently proposed. Molecular communication (MC), based on the exchange of information by releas-ing/absorbing molecules, is a novel communication paradigm to interconnect nanoma-chines that seems well-suited to the nano-scale, specially, when intra-body scenarios for medical

by means of free diffusion. An information theoretical analysis of diffusion-based MC is required to better understand the potential of this novel communication mechanism. The study and the modeling of the noise sources is of utmost importance for this analysis. The objective of this paper is to provide a

Arrival Modeling and Error Analysis for Molecular Communication via Diffusion with Drift

by H. Birkan Yilmaz, Chan-byoung Chae, Burcu Tepekule, Ali E. Pusane
"... Abstract—The arrival of molecules in molecular communi-cation via diffusion (MCvD) is a counting process, exhibiting by its nature binomial distribution. Even if the binomial pro-cess describes well the arrival of molecules, when considering consecutively sent symbols, the process struggles to work ..."
