Preface
Wireless spectrum is a scarce resource, and historically it has been divided into chunks and allocated to different government and commercial entities with longterm and exclusive licenses. This approach protects license users from harmful interferences from unauthorized users, but leaves little spectrum for emerging new services and leads to low spectrum utilizations in many spectrum bands. The way to turn spectrum drought into spectrum abundance is to allow dynamic and opportunistic spectrum sharing between primary licensed and secondary unlicensed users with different priorities. Such sharing is becoming technologically feasible due to the recent advances such as cognitive radio and small cell technologies, which allow multiple wireless devices to transmit concurrently in the same spectrum without significant mutual negative impacts. As the spectrum opportunities are often dynamically changing over frequency, time, and space due to primary users’ stochastic traffic, secondary users need to make intelligent spectrum access and sharing decisions. In this book, we propose a novel social cog
