Title: Pattern of Diffusion Recognition in a Molecular Communication Model
Abstract: A nanomachine is the basic functional unit in nanotechnology that can perform simple tasks, like sensing and actuation. A set of nanomachines can perform more complex tasks through communicating and sharing information, and by that, they form a nanonetwork. Different communication techniques are proposed for information exchange among nanomachines. Molecular communication is one of these techniques, which is a bio-inspired communication mechanism. In this paper a time slotted model consist of n nanomachines in a bounded environment is considered. These nanomachines are communicate according to diffusion based molecular communication. Information molecules are encoded based on the variation in the concentration of molecules in the communication medium. Thus, the receiver nanomachine decode the sensed information molecules during a certain time slot as '1', if its concentration exceeds a certain threshold τ, and '0' otherwise. The main objective is to study the performance of diffusion based molecular communication model, the pattern of diffusion was explored, by inspecting how a receiver nanomachine could distinguish a message from one transmitter nanomachine at a distance d or two transmitter nanomachines at different distances. The information molecules were represented as 2-bits by using 22 different values with 22 − 1 thresholds. In the implemented experiments the effects of distance, time, sensed molecular concentration and interference are considered.
