This book covers the basic concepts of UV communication, the analysis of UV channel characteristics, the organize media access protocols, and routing protocols, etc. in the network. Based on the analysis of classical communication protocols, a basic framework for UV self-organising networks is proposed. The communication protocol proposed in the book is analyzed in detail, and the key procedures of computer simulation are given at the end of the book so that readers can learn and understand. This book can guide senior undergraduate and postgraduate students of communications, networking, and other related majors in colleges and universities. It can also be used as a reference book for researchers and engineering technicians.
