Reducing Dispersion in Molecular Communications by Placing Decelerators in the Propagation Channel
In molecular communications, magnetic nanoparticles, which are injected into a pipe flow, are used as information carriers. Due to the parabolic shape of the velocity profile in laminar flow regimes, the speed of one particle depends on its radial position in the tube. This results in an unwanted extension of a particle pulse over the propagation time. Potential overlapping of subsequent pulses induces intersymbol interference. Only few research of the current state of the art reduces velocity dispersion directly within the propagation channel. To the best of the authors’ knowledge, this is the first paper that numerically investigates different passive obstacles which are placed directly in the channel for non-turbulent flow regimes to address the dispersion effects. These obstacles serve as decelerators, as they decelerate the fastest particles while at the same time accelerating slower particles. The results reveal that a passive decelerator can reduce the velocity dispersion in molecular communications and, thus, guarantee a more packetized pulse shortly behind the decelerator but also after some distance. Compared with different decelerators, an elliptical-shaped one showed the best results, as it inverts the velocity profile.
期刊介绍:
As a result of recent advances in MEMS/NEMS and systems biology, as well as the emergence of synthetic bacteria and lab/process-on-a-chip techniques, it is now possible to design chemical “circuits”, custom organisms, micro/nanoscale swarms of devices, and a host of other new systems. This success opens up a new frontier for interdisciplinary communications techniques using chemistry, biology, and other principles that have not been considered in the communications literature. The IEEE Transactions on Molecular, Biological, and Multi-Scale Communications (T-MBMSC) is devoted to the principles, design, and analysis of communication systems that use physics beyond classical electromagnetism. This includes molecular, quantum, and other physical, chemical and biological techniques; as well as new communication techniques at small scales or across multiple scales (e.g., nano to micro to macro; note that strictly nanoscale systems, 1-100 nm, are outside the scope of this journal). Original research articles on one or more of the following topics are within scope: mathematical modeling, information/communication and network theoretic analysis, standardization and industrial applications, and analytical or experimental studies on communication processes or networks in biology. Contributions on related topics may also be considered for publication. Contributions from researchers outside the IEEE’s typical audience are encouraged.
