  4. Abstract:
  5. The macro-scale molecular communication (MC) recently received considerable attention because of its potential applications. Since most of the experimental research in MC focuses on the micro-scale cases, it is necessary to study and implement experiments to investigate the concept’s feasibility as well as to validate the models and parameters. In this paper, a macro-scale flow-based MC platform with fluidic medium is developed, in a semi-cylindrical channel with laminar flow condition. The transmission medium we consider is water in the plexi pipe, a transmitter releases Hydrochloric acid molecules into this pipe and a chemical sensor is used as the receiver. We propose an LTI model for the pH-meter and obtain its parameters based on the experimental results. Next, we design the appropriate encoding-decoding schemes and implement the optimum receiver for the validated model and obtained parameters. To increase the rate, an ISI mitigating method is implemented with adaptive thresholds. In particular, an end-to-end theoretical model is proposed for this system which is confirmed by experiments as well as simulation results using COMSOL software platform. We validate our proposed model and derive related parameters both with the experimental results as well as the simulation results. The performance of the system is analyzed in terms of the bit error probability and the communication rate. IEEE
