📝 Abstract
This letter develops a one-dimensional (1D) diffusion-based molecular communication system to analyze channel responses between a single transmitter (TX) and two fully-absorbing receivers (RXs). Incorporating molecular degradation in the environment, rigorous analytical formulas for i) the fraction of molecules absorbed, ii) the corresponding hitting rate, and iii) the asymptotic fraction of absorbed molecules as time approaches infinity at each RX are derived when an impulse of molecules are released at the TX. By using particle-based simulations, the derived analytical expressions are validated. Simulations also present the distance ranges of two RXs that do not impact molecular absorption of each other, and demonstrate that the mutual imfluence of two active RXs reduces with the increase in the degradation rate.💡 Summary & Analysis
The paper explores a 1D diffusion-based molecular communication system between one transmitter (TX) and two fully-absorbing receivers (RXs). The researchers aimed to understand how molecules released from the TX are absorbed by each RX, considering environmental degradation factors. They derived analytical formulas for the fraction of molecules absorbed at each receiver, the corresponding hitting rate, and the asymptotic fraction as time approaches infinity.To achieve this, they used rigorous mathematical models that account for molecular degradation in the environment. The results were validated using particle-based simulations, which also revealed insights into how close two RXs can be without interfering with each other’s molecule absorption. As the degradation rate increases, the mutual influence between active receivers decreases, indicating a more stable and predictable communication system.
This study is significant as it advances our understanding of molecular communication systems, paving the way for practical applications in biological systems or nanotechnology where traditional electronic signals may not be feasible. The findings will aid in designing efficient and reliable molecular communication networks.
