This SpringerBrief focuses on spectrum trading designs in multi-hop cognitive radio networks. It starts with the motivation for spectrum trading and the review of existing spectrum trading designs. Then, it presents a novel CRN architecture for spectrum trading considering spectrum trading’s economic features and wireless nature. Under this network architecture, it extends current single-hop per-user based spectrum trading design into a multi-hop transmission opportunity based one, and fur...

Gene flow is a natural process that occurs spontaneously and enables the evolution of life. However, with the release of genetically modified organisms, concerns have focused on introduced foreign transgenes and their dispersal in nature through gene flow. This book examines gene flow of transgenes, such as herbicide resistance genes, with the goal of understanding the factors that may affect the process of gene flow. A greater biological understanding is essential to make sound management...

Social Support and Health in the Digital Age discusses how theinformation age has revolutionized nearly every facet of human communication—from the ways in which people purchase products to how they meet and fall in love. These exciting new communication technologies can both unite and divide us. People who are separated by great distances can now communicate with each other in real time, whereas parents often find themselves competing with smartphones and tablets for their children’s atte...

This book explores Black identity, from a global perspective. The historical and contemporary migrations of African peoples have brought up some interesting questions regarding identity. This text examines some of those questions, and will provide relevant essays on the identities created by those migrations. Following a regional contextualizing of migration trends, the personal essays with allow for understandings of how those migrations impacted personal and community identities. Each of...

Gender and Food in Transnational East Asias illustrates how the production and consumption of food impacts the changing social positions of individuals and their relationships with their families, the state, and their work, as well as shapes their gender, sexual, ethnic, and national identities. The transnational movement of food and people between East Asia and the rest of the world is increasingly visible, forming various forces behind the cultural and political constructions of gender p...

This book provides solutions to some of the issues present in the physical layer of current high-frequency wireless communication systems. It reviews the development history of high-frequency wireless communication systems, pinpoints certain existing problems in contemporary high-frequency communication systems, and proposes solutions. The 6th Generation Mobile Networks (6G) is based on terrestrial cellular networks and integrates satellite communication, drone communication, and marine co...

Data is fundamentally changing the nature of businesses and organisations and the mechanisms for delivering products and services. This book is a practical guide to developing strategy and policy for data governance, in line with the developing ISO 38505 governance of data standards.
