PROJECT TITLE :

Cooperative heterogeneous framework for spectrum harvesting in cognitive cellular network

ABSTRACT:

With the proliferation of mobile devices and emerging data-hungry applications, mobile data has been increasing dramatically. To accommodate large mobile data, the cellular network has been straining to fulfill the need thanks to the scarcity of spectrum. As a promising technology, cognitive radio can be leveraged by the cellular network to harvest spectrum holes on demand. By using cognitive radio, the cellular network becomes a cognitive cellular network. In this text, we tend to first provide an outline of the cognitive cellular network, as well as the network architecture and main applications. Then existing spectrum harvesting approaches are reviewed, and the limitations are identified. To higher explore spectrum access opportunities, 3 varieties of cooperation-based mostly approaches are introduced for various scenarios, primarily based on that an integrated cooperative framework is devised to fully harvest spectrum holes. Simulation results are provided to judge the performance of the proposed cooperative approaches.
