Variables used in the analytical model and their description.

Variable	Description
n	The number of nano-nodes, uniformly distributed, in the flow-guided nano-network, $n\ge 1$, $n\in \mathcal{N}$.
v	Average speed of the nano-node in the flow in $\mathrm{m}/\mathrm{s}$.
T	Time required by a nano-node to complete a round in the flow-guided network in $\mathrm{s}$.
f	Nano-node charging frequency in $\mathrm{Hz}$.
A	Length of the coverage area in $\mathrm{m}$.
$A_{tx}$	Length of the transmission zone in $\mathrm{m}$, $A_{tx}=A-v{t}_f$.
$A_{cx}$	Length of the collision zone in $\mathrm{m}$, $A_{cx}=A+v{t}_f$.
$\sigma$	Number of transmission slots between two battery charges, $\sigma \ge 1$, $\sigma \in \mathcal{N}$.
$t_f$	Time required to transmit a frame in $\mathrm{s}$.
