Development and implementation of technology‐neutral spectrum sharing protocols - State of the Art Assessment
Fuehrer Detlef · Joint Research Centre (European Commission) · 2012
In recent years, radio spectrum has become an increasingly scarce and valuable resource. The proliferation of wireless devices, the emergence of smartphones and the enormous increase in mobile data traffic call for the development of new, more efficient methods and technologies to use the radio spectrum. Sharing spectrum between different classes of users has been identified as a potential means to relieve the problem of spectrum scarcity, with Cognitive Radio being the most prominent enabling technology. This report intends to provide an assessment of the state-of-the-art in development and implementation of technology-neutral spectrum sharing protocols. A spectrum sharing protocol is a set of rules or a framework defining how radio spectrum may be accessed by different users. As spectrum sharing is predominantly handled within the link layer the focus of this report is on this part of the cognitive radio protocol stack.
