Interference reduction via enzyme deployment for molecular communication

In a molecular communication via diffusion (MCvD) system, enzymes are known to reduce molecular signal interference caused by eliminating unwanted chemicals that persist in the system. An MCvD system with a fixed amount of enzymes around the spherical receiver is considered. Since the enzyme amount is fixed, increasing the size of the enzyme region increases the probability of entering the enzyme region while it decreases the effectiveness of the enzymes. Therefore, the size of the enzyme region needs to be optimised. Thus, the effect of system parameters on the optimal enzyme region radius is analysed.
