Abstract— Spectrum management is used to improve performance in multiuser communication system, e.g., cognitive radio or femtocell networks, where multiuser interference can lead...
—While the polling or request/response paradigm adopted by many network and systems management approaches form the backbone of modern monitoring and management systems, the most ...
Cognitive radio (CR) techniques improve the spectrum utilization by exploiting temporarily-free frequency bands (i.e., in the time domain). The spectrum utilization can be boosted...
The network is becoming more and more versatile because of the variety of the computing resources and the communication technologies that have become available. The mobility of the...
We consider the problem of optimal channel access to provide quality of service (QoS) for data transmission in cognitive vehicular networks. In such a network the vehicular nodes ...
