A localized and distributed channel assignment framework for cognitive radio networks
The availability of multiple interfaces and channels in wireless devices is expected to alleviate the capacity limitations that exist in traditional single channel wireless mesh networks. Although having multiple radio interfaces and available channels ...
Efficient spectrum sharing and power control in cognitive radio networks
Cognitive radio technology solves the spectrum under utilization problem by enabling the secondary users access the spectrum holes opportunistically. In this paper, we are interested in how to share the spectrum holes among the secondary users, with the ...
Resource allocation for cognitive radio: a nonlinear programming approach
The design goal of the cognitive radio (CR) is to enhance the spectrum use under different environments. To achieve higher spectrum use with negligible interference to legacy users, we consider the joint resource allocation, i.e. waveform design and ...
Optimal power allocation for cognitive radio based on a virtual noise threshold
In this paper, we investigate the idea of using cognitive radio to reuse locally unused spectrum for communications. We consider a multiband/wideband system with two users in which the primary (licensed) user and the secondary (cognitive) user wish to ...
Optimizing for sparse training of Cognitive Radio networks
In order to find a configuration suitable to fulfill its needs, Cognitive Radios search the parameter configuration search space using one or more particular algorithms or heuristics. While each individual configuration tested uses a similar cost for ...
HOS-based mode classification for infomobility framework
The growing number of new emerging wireless standards is creating regulatory problems in allocating the unlicensed frequencies. A possible solution for increasing the frequency reusage within the framework of info-mobility cellular systems is the joint ...
