This paper addresses the bit error probability optimization of a DBMC-NOMA network with bio-nano-machines incapable of complex computations for classical optimization methods. We propose a pilot-symbol-based algorithm to approximate the optimal detection threshold and emitted number of transmitted molecules. Our solution is based on two algorithms for the separate optimization of thresholds and the number of molecules, which are applied alternatingly. Our Monte-Carlo simulation results show that the algorithm reliably approaches the global optimum parameter values regardless of initial values and signaling-molecule-to-noise ratio. Since it is composed of only a few basic operations, such as comparisons and additions, there is potential for an implementation using stochastic chemical reaction networks in future work.","PeriodicalId":36530,"journal":{"name":"IEEE Transactions on Molecular, Biological, and Multi-Scale Communications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10577441","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed scheme employs a Q-learning-based adaptive transceiver (a so-called QL-ADT), wherein an agent gradually learns how to adapt the transmission parameters to the current state of the channel. A real heart rate dataset is used to estimate the blood flow velocities over time, based on which a time-varying molecular channel is modelled. In the practical implementation of the QL-ADT, an external gateway, situated on the skin, monitors the body’s heart rate over time and interfaces with the NTs through implantable nano devices. The gateway dynamically adjusts the communication parameters of the NTs based on the measured heart rate and what it has learned during the training phase. The proposed QL-ADT scheme showed significant improvement in the achievable raw bit rate (RBR) and error performance for a real heart rate dataset.","PeriodicalId":36530,"journal":{"name":"IEEE Transactions on Molecular, Biological, and Multi-Scale Communications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10577429","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper studies a multiuser MMC system in a three-dimensional diffusive environment, which is composed of multiple transmitter nanomachines and one receiver nanomachine. Considering that all transmitter nanomachines release the same type of molecules for information transmission, the mechanism of time division multiple access (TDMA) is employed in this system. Under the release resource constraint which requires that the total number of released molecules of all transmitter nanomachines is fixed, the resource allocation optimization plays a significant role in the performance of this system. When the environmental variables in this multiuser MMC system change, the traditional optimization algorithms need to reoptimize the resource allocation to minimize the average bit error probability (BEP) of this system, which results in more run time. In order to reduce the run time, we propose an algorithm designed based on deep neural network (DNN) to obtain the optimal resource allocation scheme. For the trained DNN, once the input is given, it does not need to re-execute the optimization process and the output can be instantaneously obtained. The numerical results show that the proposed algorithm has a shorter run time and lower average BEP compared with other existing traditional optimization algorithms used in MMC, including bisection algorithm and genetic algorithm. The optimization results are approximate to the optimal solutions obtained by the exhaustive search. These analysis results can provide help in designing a multiuser MMC with optimal resource allocation.","PeriodicalId":36530,"journal":{"name":"IEEE Transactions on Molecular, Biological, and Multi-Scale Communications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Explicitly simulating their physical causes is computationally intensive, so it is typically preferable to simply vary the coefficients. This raises the question of how to address the boundaries between the regions. Making them fully permeable in both directions seems intuitively reasonable, but causes molecular motion to be simulated as active diffusion, meaning that it arises from energy that is continuously added to the system; in this case, molecules accumulate on the slow-diffusing side. However, molecular motion in most biochemical systems is better described as thermal diffusion, meaning that it occurs even at equilibrium. This can be simulated by reducing the transmission probability into the slow-diffusing side, which yields the correct result that spatially varying diffusion coefficients that arise from macromolecular crowding, changes in viscosity, or other energy-neutral influences do not affect equilibrium molecular concentrations. This work presents transmission coefficients and transmission probability equations for simulating thermal diffusion, including for cases with free energy differences and/or volume exclusion by crowders. They have been implemented in the Smoldyn particle-based simulation software.","PeriodicalId":36530,"journal":{"name":"IEEE Transactions on Molecular, Biological, and Multi-Scale Communications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
