本文研究了不同迁移条件下的流动诱导扩散分子通信问题，包括：1)发送端（TX）和接收端（RX）纳米机器都是可移动的；2) TX为移动，RX为固定；3) TX固定，RX移动。特别地，考虑一个点TX和一个完全吸收点RX的一维环境。利用具有正漂移的布朗运动表征纳米机器和信息分子的运动，导出了上述移动场景下首次撞击时间的概率密度函数（PDF）的封闭表达式。通过粒子模拟验证了导出的PDF表达式。基于这些结果，研究了流动诱导扩散通道中开关键控（OOK）调制的分子通信性能。特别地，导出了基于似然比检验（LRT）的决策规则的检测概率和虚警概率、错误概率以及存在符号间干扰、计数错误和其他源噪声时的可实现率的封闭表达式。仿真结果验证了理论结果，并深入了解了系统在不同移动条件下的性能。
This paper investigates the problem of flow-induced diffusive molecular communication under various mobility conditions, such as: 1) both transmitter (TX) and receiver (RX) nanomachines are mobile; 2) TX is mobile and RX is fixed; and 3) TX is fixed and RX is mobile. In particular, a 1-D environment with a point TX and a fully absorbing point RX is considered. Closed-form expressions for the probability density function (PDF) of the first hitting time under the aforementioned mobile scenarios are derived, by characterizing the movement of the nanomachines and information molecules using Brownian motion with positive drift. The derived PDF expressions are validated through particle-based simulations. Based on these results, the performance of molecular communication with on-off keying (OOK) modulation in flow-induced diffusive channels is investigated. In particular, closed-form expressions for the probabilities of detection and false alarm with likelihood ratio test (LRT)-based decision rule, probability of error, and the achievable rate in the presence of inter-symbol interference, counting errors, and noise from the other sources are derived. Simulation results are presented to verify the theoretical results and to yield insights into the system performance for different mobility conditions.
