Optimal Transmission Probability in Binary Molecular Communication

Molecular communication (MC) is a promising nanoscale communication paradigm that enables nanomachines to share information by using messenger molecules. In this paper, an expression for the achievable rate in MC is first given. Then, using this expression, an optimal transmission probability is developed to maximize the MC rate. Numerical results show that the MC rate is time-dependent and the molecules freely wandering in the medium negatively affect the MC performance. However, the proposed optimal transmission probability is shown to maximize the MC rate.
