Abstract:


Background: The architecture and sequential learning rule-based underlying ARFIS (adaptive-receiver-based fuzzy inference system) is proposed to estimate and predict the adaptive threshold-based detection scheme for diffusion-based molecular communication (DMC).

Method: The proposed system forwards an estimate of the received bits based on the current molecular cumulative concentration, which is derived using sequential training-based principle with weight and bias and an input-output mapping based on both human knowledge in the form of fuzzy IF-THEN rules. The ARFIS architecture is employed to model nonlinear molecular communication to predict the received bits over time series.

Result: This procedure is suitable for binary On-OFF-Keying (Book signaling), where the receiver bio-nanomachine (Rx Bio-NM) adapts the 1/0-bit detection threshold based on all previous received molecular cumulative concentrations to alleviate the inter-symbol interference (ISI) problem and reception noise.

Conclusion: Theoretical and simulation results show the improvement in diffusion-based molecular throughput and the optimal number of molecules in transmission. Furthermore, the performance evaluation in various noisy channel sources shows a promising improvement in the un-coded bit error rate (BER) compared with other threshold-based detection schemes in the literature.
