Molecular Communication Among Biological Nanomachines: A Layered Architecture and Research Issues

Abstract

Molecular communication is an emerging communication paradigm for biological nanomachines. It allows biological nanomachines to communicate through exchanging molecules in an aqueous environment and to perform collaborative tasks through integrating functionalities of individual biological nanomachines. This paper develops the layered architecture of molecular communication and describes research issues that molecular communication faces at each layer of the architecture. Specifically, this paper applies a layered architecture approach, traditionally used in communication networks, to molecular communication, decomposes complex molecular communication functionality into a set of manageable layers, identifies basic functionalities of each layer, and develops a descriptive model consisting of key components of the layer for each layer. This paper also discusses open research issues that need to be addressed at each layer. In addition, this paper provides an example design of targeted drug delivery, a nanomedical application, to illustrate how the layered architecture helps design an application of molecular communication. The primary contribution of this paper is to provide an in-depth architectural view of molecular communication. Establishing a layered architecture of molecular communication helps organize various research issues and design concerns into layers that are relatively independent of each other, and thus accelerates research in each layer and facilitates the design and development of applications of molecular communication.

Biologically Inspired Bio-Cyber Interface Architecture and Model for Internet of Bio-NanoThings Applications

“…Depending on the molecules to be detected, the probe can be complementary biochemical molecules such 13 as monoclonal antibodies [38]. The detection process can be a ligand-receptor binding action between the circulating information molecule and the receptor probe.…”

Framework for dependable and pervasive eHealth services

“…Bio-nanomachines interacting with their environment include DNA (deoxyribonucleic acid) sequences, genetically programmed bacteria and engineered cells [25]. Bacteria may act as DNA carriers.…”

“…Bacteria may act as DNA carriers. Functionalities of a bio-nanomachine are listed in [25] together with open research issues in this emerging area. Among the most interesting interactions is the brain-machine interface [26].…”

“…Open research issues include the control of nanomachines, robustness to deterioration (consistency of behavior) of bionanomachines subject to decline, and dismissal of nonfunctioning machines [25].…”

On the Interaction between a Nanoparticulate System and the Human Body in Body Area Nanonetworks

“…Molecular communication (MC) is largely exploited for nanonetworks [8,10,11]. This is a novel communication paradigm, envisaged as the most practical way in which nanorobots can communicate with each other by the use of molecules as information carriers.…”
