Reliability Analysis of Molecular Communication Based on Drift Diffusion

Molecular communication is a novel nanoscale communication method. The information can be encoded by using different molecules for transmission. However, as a result of various symbol molecules are easy to interfere with each other and the stochastic behaviour of the molecules, molecular communication is easily susceptible to a low reliability. Therefore, reliability is a vital issue in the field of molecular communication. At present, the reliability analysis of existing molecular communication has not taken the drift velocity into consideration. In this paper, we introduce the drift velocity of molecules and propose a reliability model of molecular communication based on drift diffusion in the single link and single path. Furthermore, retransmission mechanism is introduced on the condition of the transmission failure. Finally, our simulation experiments show how the parameters in the model affect the reliability of molecular communication based on drift diffusion, which can guide us how to improve the reliability of molecular communication based on drift diffusion in the future.
