Abstract

Active transport such as fluid flow is sought in molecular communication
to extend coverage, improve reliability, and mitigate interference.
Flow models are often over-simplified, assuming one-dimensional
diffusion with constant drift. However, diffusion and flow are usually
encountered in three-dimensional bounded environments where the flow is
highly non-uniform such as in blood vessels or microfluidic channels.
For a qualitative understanding of the relevant physical effects
inherent to these channels, based on the Peclet number and the
transmitter-receiver distance, we study when simplified models of
uniform flow and advection-only transport are applicable. For these two
regimes, analytical expressions for the channel impulse response are
derived and validated by particle-based simulation. Furthermore, as
advection-only transport is typically overlooked and hence not analyzed
in the molecular communication literature, we evaluate the symbol error
rate for exemplary on-off keying as performance metric.
