What Really is `Molecule' in Molecular Communications? The Quest for Physics of Particle-based Information Carriers
Molecular communication, as implied by its name, uses molecules as
information carriers for communication between objects. It has an advantage
over traditional electromagnetic-wave-based communication in that
molecule-based systems could be biocompatible, operable in challenging
environments, and energetically undemanding. Consequently, they are envisioned
to have a broad range of applications, such as in the Internet of Bio-nano
Things, targeted drug delivery, and agricultural monitoring. Despite the rapid
development of the field, with an increasing number of theoretical models and
experimental testbeds established by researchers, a fundamental aspect of the
field has often been sidelined, namely, the nature of the molecule in molecular
communication.
The potential information molecules could exhibit a wide range of properties,
making them require drastically different treatments when being modeled and
experimented upon. Therefore, in this paper, we delve into the intricacies of
commonly used information molecules, examining their fundamental physical
characteristics, associated communication systems, and potential applications
in a more realistic manner, focusing on the influence of their own properties.
Through this comprehensive survey, we aim to offer a novel yet essential
perspective on molecular communication, thereby bridging the current gap
between theoretical research and real-world applications
