Auction based spectrum trading for cognitive radio networks
Tehrani, M. N.; Uysal, Murat (IEEE, 2013-06)In this letter, we consider the shared used model in cognitive radio networks and design a spectrum trading method to maximize the total satisfaction of the Secondary Users (SUs) and revenue of the Wireless Service Provider ... -
Device-to-device communication in 5G cellular networks: challenges, solutions, and future directions
Tehrani, M. N.; Uysal, Murat; Yanikomeroglu, H. (IEEE, 2014-05)In a conventional cellular system, devices are not allowed to directly communicate with each other in the licensed cellular bandwidth and all communications take place through the base stations. In this article, we envision ... -
Pricing for open access femtocell networks using market equilibrium and non-cooperative game
Tehrani, M. N.; Uysal, Murat (IEEE, 2012)In this paper, we address the pricing problem in open-access femtocell networks. We use economic and game theoretic approaches such as market equilibrium and non-cooperative game to propose novel pricing schemes. In our ... -
Sensing-throughput tradeoff in cooperative spectrum sensing
Tehrani, M. N.; Uysal, Murat (IEEE, 2012)In the current literature on cognitive radio, it is commonly assumed that fixed time durations are assigned for spectrum sensing and data transmission. It is however possible to improve the performance by finding the best ... -
Spectrum trading for non-identical channel allocation in cognitive radio networks
Tehrani, M. N.; Uysal, Murat (IEEE, 2011)In this paper, we investigate spectrum trading via auction approach for cognitive radio networks. We consider a realistic valuation function in terms of different parameters for secondary users (SUs), and propose an efficient ... -
Spectrum trading for non-identical channel allocation in cognitive radio networks
Tehrani, M. N.; Uysal, Murat (IEEE, 2013)In this paper, we investigate spectrum trading via auction approach for exclusive usage spectrum access model in cognitive radio networks. We consider a realistic valuation function which depends on channel capacity, delay ... -
Spectrum trading for risky environments in IEEE 802.22 cognitive networks
Tehrani, M. N.; Uysal, Murat (IEEE, 2011)In this paper, we consider the shared used model in the context of IEEE 802.22 cognitive and investigate spectrum trading via auction approach. We consider two different scenarios in which the dominant risk is either ...
