Active flow network

An active flow network is a graph with edges and nodes, where particles inside this graph are propelled by an active mechanism. This type of network is used to study the motion of molecules in biological medium. Examples are organelles, including the Endoplasmic Reticulum (ER). The mechanism of the flow between nodes is actively driven, as opposed to passive transport by diffusion. Active transport requires energy consumption, found in the form of ATP in biological systems. The slime mold Physarum polycephalum is also growing as a network , where motion inside is driven an active flow.
