Multiple-Type Transmission Multiple-Type Reception Framework on Molecular Communication

摘要

In this letter, we propose a new multiple-input multiple-output (MIMO) molecular communication (MC) system where multiple types of molecules are utilized for transmission and reception of information. We call the proposed framework multiple-type transmission multiple-type reception (MTMR). The receiver nanomachines in the proposed scheme are based on the ligand receptors. For the bidirectional communication between the nanomachines, we consider two-way MC. We also obtain the bit error rate (BER) of the system, and an optimization problem is formulated to minimize BER by optimizing the drug dosage for designing a drug release mechanism. As numerical analysis shows, the BER of MIMO-MTMR in MC is minimized to 10(-6) by considering the budget of molecules as 5000 for each transmitter. Furthermore, MIMO-MTMR outperforms single-type transmission single-type reception MIMO from the BER performance point of view as discussed in the numerical analysis.
