Query: Big Spectrum Data: The New Resource for Cognitive Wireless Networking   The era of Big Data is here now, which has brought both unprecedented
opportunities and critical challenges. In this article, from a perspective of
cognitive wireless networking, we start with a definition of Big Spectrum Data
by analyzing its characteristics in terms of six Vs, i.e., volume, variety,
velocity, veracity, viability, and value. We then present a high-level tutorial
on research frontiers in Big Spectrum Data analytics to guide the development
of practical algorithms. We also highlight Big Spectrum Data as the new
resource for cognitive wireless networking by presenting the emerging use
cases.
