Design of macroscopic air-based molecular communication concept using fluorescein

Abstract

A proof of concept for a macroscopic air-based molecular communication testbed is presented using fluorescein. The compound in solution state when excited by ultra-violet light, acts as information carrier between a sprayer (transmitter) and a camera (receiver). Relatively higher data rates can be achieved compared to traditional air-based testbeds using alcohol. Implemented modulation schemes include on-off keying, pulse position modulation and differential pulse position modulation, which showcase the efficacy of the system in terms of achievable data transmission rates.
