We consider the problem of characterizing the first arrival position (FAP) density in molecular communication (MC) with a diffusion-advection channel that permits a constant drift velocity pointed to arbitrary direction. The advantage of FAP modulation lies in the fact that it could encode more information into higher dimensional spatial variables, compared to other modulation techniques using time or molecule numbers. However, effective methods to characterize the FAP density in a general…

Capacity of First Arrival Position Channel in Diffusion-Based Molecular Communication

The main contribution in this paper is a complete characterization of the zero-drift FAP channel capacity for the 2D and 3D spaces and the application of a modified logarithmic constraint as a replacement of the usual power constraint.

Distribution of first arrival position in molecular communication

A mathematical framework is developed to obtain the closed-form density function of the first arrival position for particles/molecules diffusing under constant net drift, which provides a novel analytical framework for existing molecular communication systems but may inspire novel molecular communication system design.

Molecular Communication in Fluid Media: The Additive Inverse Gaussian Noise Channel

It is shown that the use of multiple molecules leads to reduced error rate in a manner akin to diversity order in wireless communications, and that the additive inverse Gaussian noise channel model is appropriate for molecular communication in fluid media.
