Molecular communication is a nanoscale communication
method in which information is encoded in molecules. Molecular
communication using microtubules in free space is one of the
realistic scenarios proposed for this type of nanocommunication.
Based on this technique, molecular communication via filaments
using nano-relays is proposed in this paper to improve the performance
of the system in terms of delay and bit error probability.
An analytical model using jump diffusion processes is proposed for
molecular propagation in this scenario. It is shown that the proposed
mathematical model is capable of tracking molecular propagation
in molecular communication via filaments using nano-relays.
Also, the model is used to investigate effects of different parameters
on delay and bit error probability.
