“…However, for extending the range of data transmission in channels with high attenuation and/or distortion, relays are commonly used. In MC, too, this approach has been adopted and investigated [27], [28]: diffusion-based 2-hop processes, i. e., with a single relay between transmitter and receiver in the 1- [29], [30], 2-[31] and 3-dimensional space [32], [33], have been presented, where both a mere amplification of the received signal (amplify-and-forward) and a decoding and subsequent encoding of the reconstructed message (decode-and-forward) were considered. Also the effect of an additional drift component was studied in [34]- [37].…”

In order to enable molecular communication on macroscopic distances without a moving medium, the model of diffusion-based information transmission with a large number of relays suspended in the medium, hence at random positions, is proposed. With an increasing number of relays, the stochastic variations approach zero and the system exhibits a quasideterministic behavior. Furthermore, the transmission time becomes inversely proportional to the number of relays and the impulse response independent of the channel length. Thus, the model describes a wave-like propagation, which is fundamentally different from the established flow-and diffusion-based approaches in molecular communication.

Modulation Analysis in Macro-Molecular Communications

Molecular communication (MC) involves the transmission of information using particles (i.e., molecules). Research into the field has been dominated by micro-scale, and most of the effects of macroscale communication have yet to be studied. In this paper, the modulation and transmission of MC at macroscale are investigated. For the transmitter, an in-house-built odor generator was used, and as the detector, a mass spectrometer with a quadrupole mass analyzer was employed. Various 2-level, 4-level, and 8-level modulation schemes were tested experimentally. A simulation framework, developed for the first time, was used for comparison with the experimental results. It was shown that communication can be modeled using a variant of the advection-diffusion equation and that it gives good agreement with the experimental results. A symbol-error-rate (SER) analysis of both the experimental and simulation results was analyzed. It was found that increasing the distance has a detrimental effect on both the channel capacity and the SER, whereas velocity and diffusivity have a decreasing effect on the SER and an increasing effect on the channel capacity. A channel model was developed based on the asymmetric behavior of the communications, and the optimal sampling period was developed that subsequently permitted analysis of the ISI of the communications scheme. INDEX TERMS Macro-scale, mass spectrometer, asymmetric channel, bit-error rate, molecular intersymbol interference.
