We consider the problem of opportunistic dynamic spectrum access (DSA) in an ad hoc
network in which unlicensed secondary users communicate through channels not used by …

In this paper, we provide a survey of dynamic spectrum access techniques. Various
approaches envisioned for dynamic spectrum access are broadly categorized under three …

With the increasing demands for radio spectrum, techniques are being explored that would
allow dynamic access of spectrum bands that are under-utilized. In this regard, a new …

Dynamic spectrum allocation (DSA) seeks to exploit the variations in the loads of various
radio-access networks to allocate the spectrum efficiently. Here, a spectrum manager …

Dynamic spectrum sharing has become an important approach to improve spectrum
efficiency by exploiting traffic loads variations of multiple wireless networks when a radio …

We consider dynamic spectrum allocation in the downlink between multiple service
providers and users, and develop a model that is applicable for many future scenarios. The …

The radio frequency spectrum is a naturally limited resource of extraordinary value, as the
key to the provision of important communication and information services. Traditionally …

It is expected that in future user-centric wireless network scenario the concept of dynamic
spectrum trade will provide operators with opportunities to utilize the spectrum more …

An economic driven JRRM algorithm is introduced in a multicell scenario based on
guaranteeing a certain user acceptance probability of a given service while at the same time …
