受分子寿命影响的中继最大可达传输速率
Relay maximum achievable transmission rate affected by molecular lifetime
摘要
Abstract
Diffusion-based molecular communication makes molecules as the information carrier for the information transmission,the molecules do Brownian motion in the channel,following the Fick's law.With the diffusion distance increasing,the molecular concentration is rapidly attenuated,resulting in a very low channel achievable transmission rate.Therefore,relay can be used to improve the transmission performance.In view of the transmission rate in diffusion-based molecular communication relay channel is a hot spot in the field of research,this paper adopts the ligand-receptor binding mechanism,considering the molecular lifetime,molecular reach probability and other impact factors,and study the influence of achievable transmission rate in diffusion-based molecular communication,the paper study also investigates the effect of relay achievable transmission rate in the relay node location based on molecular lifetime.The simulation results show that with the molecular lifetime increasing,the time of the molecules in the channel increases,and the maximum transmission rate increases.At the same time,with the molecular lifetime increasing,the relay node need to approach to the receiver node so as reach the maximum transmission rate.关键词
