This brief examines current research on improving Vehicular Networks (VANETs), examining spectrum scarcity due to the dramatic growth of mobile data traffic and the limited bandwidth of dedicated vehicular communication bands and the use of opportunistic spectrum bands to mitigate congestion. It reviews existing literature on the use of opportunistic spectrum bands for VANETs, including licensed and unlicensed spectrum bands and a variety of related technologies, such as cognitive radio, WiFi and device-to-device communications. Focused on analyzing spectrum characteristics, designing efficient spectrum exploitation schemes, and evaluating the date delivery performance when utilizing different opportunistic spectrum bands, the results presented in this brief provide valuable insights on improving the design and deployment of future VANETs.

This book systematically and comprehensively studies on alternative media in Taiwan, using a historical approach and primary data and first hand collected materials to examine how political openness and social movement in the 1980s through the 1990s in Taiwan enabled the rapid growth and wide development of Taiwan’s alternative media, what impact the alternative media in Taiwan had on its socio-political transformation, and what implications Taiwan’s case of alternative media has for other societies, especially for other Asian societies. This book would be a good reading for intellectuals, media professionals, government analysts, and the general public as well, who are interested in this topic.

This book provides a comprehensive overview of wireless technologies for industrial network systems. The authors first describe the concept of industrial network systems and their application to industrial automation. They then go on to cover the role of sensing and control in industrial network systems, and the challenge of sensing and control in the industrial wireless environment. Then, the existing techniques for resource efficiency information transmission are introduced and studied. Afterward, the authors introduce sensing and control-oriented transmission for industrial network systems, which take advantage of spatial diversity gain to overcome the interference and fading, which in turn improves the transmission reliability without expending extra spectrum resources and enlarging the transmission delay. Subsequently, edge assisted efficient transmission schemes are introduced, which integrate the capacities of communication, computing, and control to relieve the contradiction of resource limitation and massive data. Finally, the authors discuss open research issues and future works about information transmission in industrial network systems. Presents the uses of wireless technologies for industrial network systems, and their application to industrial automation; Discusses the role of sensing and control in industrial network systems, and the challenge of sensing and control in the industrial wireless environment; Includes open research issues and future works about information transmission in industrial network systems.
