Optimal Cooperative Internetwork Spectrum Sharing for Cognitive Radio Systems With Spectrum Pooling

摘要: Spectrum pooling in cognitive radio systems is an approach to manage the available spectrum bands from different licensed networks. Most previous work on concentrates system architecture and design of flexible-access algorithms schemes. In this paper, we present a cooperative scheme for internetwork sharing among multiple secondary systems, which takes into account price efficiency as criteria. Specifically, spectrum-sharing problem formulated stochastic bandit system; thus, optimal simply allocating new band network with lowest index. Extensive simulation examples illustrate that proposed significantly improves performance compared existing ignores sharing.
