Cooperative spectrum sensing has been shown to be an effective method to improve the
detection performance of the licensed user availability by exploiting spatial diversity …

Based on the vast and elastic cloud computing resource, a cloud-based cognitive radio
access networking (C 2-RAN) service model is studied in this work. Integrating the cross …

Existing wireless networks are unable to fulfill the insatiable demand of radio spectrum by
emerging wireless services and applications. To address the current spectrum scarcity …

In this paper, we introduce the application of CR-based spectrum sharing concepts to
enable opportunistic relaying operations in cellular networks. In particular,(i) we build on …

Traditional static spectrum allocation policies have been to grant each wireless service
exclusive usage of certain frequency bands, leaving several spectrum bands unlicensed for …

As Vehicular Ad hoc Networks (VANETs) attract a lot of research attention, VANETs with
Cognitive Radio (CR-VANETs) are also studied as supplement and enhancement of …

Traditional wireless networks including wireless sensor networks working in an unlicensed
spectrum band are suffered from uncontrolled interference, as this unlicensed spectrum …

Cognitive radio (CR) vehicular networks are poised to opportunistically use the licensed
spectrum for high bandwidth inter-vehicular messaging, driver-assist functions, and …

Because of expensive capital investment and severe shortage of resources (including sites,
Wireless spectrum resources and so on), network sharing and Mobile Virtual Network …

The main challenge with Vehicular Ad-Hoc Networks (VANETs) for assisting Intelligent
