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.
