Modeling of Cognitive Mobile Molecular Communication in a Biological Microfluidic Cylindrical Channel

In the field of targeted drug delivery and pathogenesis monitoring, a Diffusive Molecular Communication (DMC) channel is considered a promising channel model. While the current DMC state-of-the-art literature provides in-depth analysis for channel modeling across various molecular communication systems, it does not include the realistic scenarios of mobile molecular communication, which are crucial for targeted drug delivery systems. In this work, a micro-cylindrical channel for a DMC system similar to a human blood vessel is modeled, considering the coexistence of a primary and a secondary link in a mobile molecular communication scenario. Further, the priority of the primary link is considered to be higher than that of the secondary link. The proposed model overcomes the limitations of previous work by formulating the Concentration Green's Function (CGF) for biological cylindrical channels. It considers the mobility of the receiver and asymmetry in the radial, axial, and azimuthal directions. Furthermore, the effect of various channel parameters such as anomalous diffusion, degradation rate, and channel radius on the concentration observed at the receiver is also shown.
