论文摘要
分子通信（MC）允许纳米机器在流体环境中相互交流和合作。基于扩散的MC很流行，但由于分子浓度严重衰减而受到发射距离的限制。在这封信中，我们为基于扩散的MC系统中的可逆结合受体提供了解释和前向（DF）继电器策略。根据接收器表面的配体和受体之间的可逆关联和分离的信息分子的时变空间分布，是表征的。得出了评估预期误差概率的分析表达，并利用影响性能的关键因素。结果表明，通过恒定的分子预算，该建议可以显着提高性能，并且可以通过优化继电器节点的位置以及分配给源节点的分子数来提高性能增长。
Molecular communication (MC) allows nanomachines to communicate and cooperate with each other in a fluid environment. The diffusion-based MC is popular but is easily constrained by the transmit distance due to the severe attenuation of molecule concentrations. In this letter, we present a decode-and-forward (DF) relay strategy for the reversible binding receptor in the diffusion-based MC system. The time-varying spatial distribution of the information molecules based on the reversible association and dissociation between ligand and receptor at the surface of receiver is characterized. An analytical expression for the evaluation of expected error probability is derived, and the key factors impacting on the performance are exploited. Results show that with a constant molecular budget, the proposal can improve the performance significantly, and the performance gain can be enhanced by optimizing the position of the relay node and the number of molecules assigned to the source node.
