Abstract

In this paper, we propose an analysis of the transmission success probability in a Förster resonance energy transfer (FRET)-based molecular communication system. FRET is an energy transmission process between molecules in close proximity without radiation of a photon. Since FRET has low dependency on environmental factors and a relatively wide transmission range, it has become a promising means of propagation in molecular communication. However, the limited availability of current research in the literature hampers comprehensive understanding of FRET capabilities in the context of wireless communication in general and molecular communication specifically. In this paper, we model a FRET-based communication system with relays and analyze its channel characteristics. We derive a theoretical expression for the successful transmission probability of the system under on-off keying modulation and the corresponding system capacity. Our analysis shows that performance of the proposed FRET system is influenced by parameters that include the FRET rate, the intrinsic fluorescence rate, and symbol duration. Furthermore, our analysis maintains a high level of accuracy, regardless of whether the relays share the same FRET rate or possess different FRET rates. Via simulations our analysis is verified in various environments.

基于多跳fret的分子通信信道特性研究

本文提出了一种基于Förster共振能量传递（FRET）的分子通信系统的传输成功率分析方法。FRET是一个能量传输过程的分子之间在接近没有辐射的光子。由于FRET对环境因素的依赖性低，传输范围相对较宽，在分子通信中已成为一种很有前途的传播手段。然而，目前文献中有限的可用性研究阻碍了对FRET在一般无线通信和具体分子通信背景下的能力的全面理解。在本文中，我们建立了一个具有中继的基于fret的通信系统模型，并分析了它的信道特性。导出了开关键控调制下系统成功传输概率和相应系统容量的理论表达式。我们的分析表明，所提出的FRET系统的性能受到参数的影响，包括FRET率，本征荧光率和符号持续时间。此外，无论继电器是否具有相同的FRET速率或具有不同的FRET速率，我们的分析都保持了高水平的准确性。通过仿真，我们的分析在不同的环境中得到了验证。

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.
