The topics addressed in this book are crucial for both the academic
community and industry, since the vehicular network has become an
essential building block for intelligent transportation systems. The
systematic principle of this book provides valuable guidance on the
deployment and implementation of V2X-enabled road-safety applications.
In addition, this book carries out structured technologies from the MAC
layer to the link and network layer, which can provide a general
introduction for interested readers with a comprehensive understanding
of applying vehicular networks in enhancing road safety, and offers a
systematized view for researchers and practitioners in the field of
vehicular networks to help them optimize and improve the desired
vehicular communication systems.
Road safety has always been the first priority for daily commuters on
the road. Vehicular networks can be an effective solution to enhance
road safety, via which vehicles can exchange cooperative awareness
messages rapidly, contributing to better situation awareness and
maneuvering cooperation. However, with the fast-changing network
topology, intermittent wireless link, and dynamic traffic density, it is
challenging to achieve satisfying network performance.
This book introduces the background of vehicular networks, provides a
comprehensive overview of networking techniques in supporting
road-safety applications, states the technical motivations per the MAC,
link, and network layer, and proposes/designs vehicular networking
technologies at the corresponding layer respectively to guarantee
low-latency and reliable V2X communications for road-safety
applications. By extending the proposed networking technologies to
support all types of vehicular services, this book also outlines open
issues and research directions in future 5G and beyond vehicular
networks.
