Molecular communication via diffusion is the state-of-the-art communication paradigm in which information is transmitted between nanomachines through molecules. It enables individual nanomachines to expand their collaborative operability in several applications. The success of molecular communication is greatly hindered by the degradation in the receiver reception performance over the channel. Although the receiver can be reinforced with the protrusions, they have still design issues to be resolved in order to improve the performance further. In this paper, we (1) propose the protrusion location optimization problem by modelling the protrusions as individual features, (2) present ten different algorithms to optimize their locations on the receiver surface and (3) measure the performance of the algorithms with probability of hit metric in two different settings. The experimental results show that Gaussian-distributed protrusions (GP) is superior in shorter channels while uniformly distributed protrusions (UP) is superior in longer channels.
