Channel Design and Optimization of Active Transport Molecular Communication

In this paper, a guideline is provided for design and optimization of the shape of active transport molecular communication channels. In particular rectangular channels are considered and it is shown that for channels employing a single microtubule as the carrier of the information particles, the smaller the perimeter of the channel, the higher the channel capacity. Furthermore, it is shown that when channels with similar perimeters are considered, square-like channels achieve higher channel capacity for small values of time per channel use, while narrower channels achieve higher information rates for larger values of time per channel use.
