Modeling nanonetworks connectivity in the blood flow

What is it about?

his work addresses a study of the connectivity of a cohort of nanorobots in the circulatory system (blood). This allows cooperative actions such as targeted drugs delivery and sensing (temperature, PH, disease indicators, etc.) that could help to detect malfunctions in the organism at an early stage. Interconnecting nanomachines in a nanonetwork overcomes the limitations of individual nanodevices expanding their capabilities in terms of both complexity and range of operation, by allowing them to coordinate and share information. The trajectories of the nanorobots are computed according their velocity, type of flow (laminar vs turbulent varying the diameter and length). On the other hand, THz omnidirectional and optical directional communications are considered where ranges are around 10 mm. Connectivity results show a strong dependency of the diameter of the vessel, the larger the better. Moreover, capillary vessels are not considered as nanorobots are very sparse requiring a huge number for useful utilization.
