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 …
This SpringerBrief presents intelligent spectrum sharing technologies for future wireless communication systems. It explains the widely used opportunistic spectrum access and TV white space sharing, which has been approved by the FCC. Four new technologies to significantly increase the efficiency of spectrum sharing are also introduced. The four technologies presented are Dynamic Spectrum Co-Ac…

T…
This open access book follows the development rules of network technical talents, simultaneously placing its focus on the transfer of network knowledge, the accumulation of network skills, and the improvement of professionalism. Through the complete process from the elaboration of the theories of network technology to the analysis of application scenarios then to the design and implementation o…
This open access book provides new conceptualisations on the networks of migrants and their descendants in accessing the labour market. Although references to social networks are common in discussions of migration, simplified ideas of co-ethnic networks often obscure the reality, for example confounding ties with co-ethnics and ‘strong ties’. This open access book addresses key questions ab…

Most of us have gone online to search for information about health. What are the symptoms of a migraine? How effective is this drug? Where can I find more resources for cancer patients? Could I have an STD? Am I fat? A Pew survey reports more than 80 percent of American internet users have logged on to ask questions like these. But what if the digital traces left by our searches could show doct…
We are active with our mobile devices; we play games, watch films, listen to music, check social media, and tap screens and keyboards while we are on the move. In Mood and Mobility, Richard Coyne argues that not only do we communicate, process information, and entertain ourselves through devices and social media; we also receive, modify, intensify, and transmit moods. Designers, practitioners, …
"The human brain is often described as the most complex object in the universe. Tens of billions of nerve cells-tiny tree-like structures--make up a massive network with enormous computational power. In this book, Giorgio Ascoli reveals another aspect of the human brain: the stunning beauty of its cellular form. Doing so, he makes a provocative claim about the mind-brain relationship. If each n…
This open access book improves the users' skills needed to implement models for performance evaluation of digital infrastructures. Building a model is usually a relatively easy task, but making it an accurate representation of the phenomenon to be reproduced is a completely different matter. It is well-known that to increase the ability to build reliable models it is necessary to accumulate exp…
