Cooperative Game-Theoretic Approach to Spectrum Sharing in Cognitive Radios
In this paper, a novel framework for normative modeling of the spectrum sensing and sharing problem in cognitive radios (CRs) as a transferable utility (TU) cooperative game is proposed. Secondary users (SUs) jointly sense the spectrum and cooperatively detect the primary user (PU) activity for identifying and accessing unoccupied spectrum bands. The games are designed to be balanced and super-...
متن کاملCognitive Radios for Spectrum Sharing
Wireless systems require spectrum to operate, but interference is likely if radios in physical proximity simultaneously operate on the same band. Therefore, spectrum is a potentially scarce resource; across the planet today, spectrum is regulated so that most bands are allocated exclusively to a single system licensed to use that band in any given location. However, such static spectrum allocat...
متن کاملA Cooperative Temporal Spectrum Sharing Game in Cognitive Radio Network
In Cognitive Radio Network, one of the most important issues is spectrum sharing between secondary users. We propose a novel approach to the cooperative spectrum sharing with the use of potential game model in Game Theory. So far, previous work on this problem have assumed that the number of network agents is fixed. However, in real-world networks, the communications loads, i.e. the number of u...
متن کاملCognitive Radios for Spectrum Sharing: Technical Appendices
This is a technical appendix to the paper titled Cognitive Radios for Spectrum Sharing which will appear in the January issue of the IEEE Signal Processing Magazine. Due the severe space constraints the technical details had to be moved out of the paper and incorporated into this report. I. TECHNICAL DETAILS FOR FIGURE 1 To calculate the available white space we retrieved the FCC’s transmitter ...
متن کاملSpectrum sharing in multi-channel cooperative cognitive radio networks: a coalitional game approach
In this paper, we study a coalitional game approach to resource allocation in a multi-channel cooperative cognitive radio network with multiple primary users (PUs) and secondary users (SUs). We propose to form the grand coalition by grouping all PUs and SUs in a set, where each PU can lease its spectrum to all SUs in a time-division manner while the SUs in return assist PUs’ data transmission a...
