Academics tend to think they are each the next Einstein whose 'creativity' will finally be uncovered a hundred years from now. That's when society sh… - Stephen F Bush

Having presented all the relevant nanoscale mechanisms, thus laying down a firm background for the readers' understanding, the author moves to the topic of architectural challenges in Chapter 7. This field is claimed still to be an unsolved problem so the author gives examples of currently used technologies and points out potential architectural solutions such as self-assembly, carbon nanotubes, or quantum systems. That is why it makes the book even more valuable for those who intend to involve nanonetworks in their research.

The advantage of molecular messaging over other sorts of communication, he says, is its ability to be deployed in hard-to-reach places, such as providing in-body communications for medical applications. The body's cellular signalling pathways have already been mapped, so these could serve as "communications channels", says Dr Bush. Digital signals could be sent, say, to the vagal system to help moderate a patient's blood pressure or heart rate. Data transmitted molecularly might also enable blood-sugar levels to be monitored without invasive pinpricks.

...Nanoscale Communication Networks is a very good and valuable book.
