    Kolmogorov turbulence and information dissipation in molecular communication
    (IEEE, 2021-02-19) Abbaszadeh, Mahmoud; Huang, Yu; Thomas, Peter J.; Wen, Miaowen; Ji, Fei; Guo, Weisi
    Waterborne chemical plumes are studied as a paradigm for representing a means for molecular communication in a macro-scale system. Results from the theory of fluid turbulence are applied and interpreted in the context of molecular communication to characterize an information cascade, the information dissipation rate and the critical length scale below which information modulated onto the plume can no longer be decoded. The results show that the information dissipation decreases with increasing Reynolds number and that there exists a theoretical potential for encoding smaller information structures at higher Reynolds numbers.

    Molecular signal tracking and detection methods in fluid dynamic channels
    (IEEE, 2020-07-17) Abbaszadeh, Mahmoud; Atthanayake, Iresha; Thomas, Peter J.; Guo, Weisi
    This method and data paper sets out the macro-scale experimental techniques to acquire fluid dynamic knowledge to inform molecular communication performance and design. Fluid dynamic experiments capture latent features that allow the receiver to detect coherent signal structures and infer transmitted parameters for optimal decoding. This paper reviews two powerful fluid dynamical measurement methodologies that can be applied beneficially in the context of molecular signal tracking and detection techniques. The two methods reviewed are Particle Image Velocimetry (PIV) and Planar Laser-Induced Fluorescence (PLIF). Step-by-step procedures for these techniques are outlined as well as comparative evaluation in terms of performance accuracy and practical complexity is offered. The relevant data is available on IEEE DataPort to help in better understanding of these methods
