Are you involved in designing the next generation of wireless networks? With spectrum
becoming an ever scarcer resource, it is critical that new systems utilize all available …

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 …

The concept of dynamic spectrum access will allow the radio spectrum to be traded in a
market like scenario allowing wireless service providers (WSPs) to lease chunks of spectrum …

In the future, we can expect to see more dynamic service offerings and profiles, as users
move from long-term service provider agreements to more opportunistic service models …

Cognitive radio (CR) has the potential for resolving the spectrum scarcity issue in wireless
communications. A CR device can establish unharmful links in the spectrum of the legacy …

As the mobile data traffic continues to grow rapidly, spectrum availability is a major concern.
Furthermore, the fixed spectrum allocation to the mobile network operators (MNOs) and lack …

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 …

Inter-operator spectrum sharing in a wide-area broadband network is considered in this
paper. A packet-based cellular model is developed, emphasizing the shift in the …

To tackle the challenge of providing higher data rates within limited spectral resources we
consider the case of multiple operators sharing a common pool of radio resources. Four …
