Abstract
In-vivo Wireless Nanosensor Networks (iWNSNs) consist of nano-sized communicating devices with unprecedented sensing capabilities that operate inside the human body in real-time. The current state-of-the-art in nanoelectronics and nanophotonics points to the Terahertz (THz) band (0.1–10 THz) and the optical frequency bands (infrared, 30–400 THz, and visible, 400–750 THz) as the promising spectral bands for nanosensor communications. In this paper, we propose and analyze a biocompatible modulation technique for iWNSNs. A mathematical framework is formulated to optimize the parameters of an adaptive Time Spread On-Off Keying (OOK) pulse-based modulation. This optimization considers both the physics of the intra-body optical channel and the light-matter interactions, along with the resulting photo-thermal effects in biological tissues. The outcomes of the analytical optimization model are validated through extensive numerical simulations. The results highlight a trade-off between link efficiency and the biocompatibility of the transmitted signals. Numerical analysis shows that the proposed biocompatible modulation technique can easily achieve a Bit Error Rate (BER) of
$10^{-2}$
before coding, within the bio-safety measures, indicating a reliable intra-body channel for data transmission. This means that the channel can effectively convey information, such as health monitoring data or control signals for medical devices, without significant data loss or corruption.
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.
