Network-coded cooperative systems in cognitive radio networks
(IEEE, 2022-12)We study the performance of a network-coded cooperative (NCC) system in an underlay cognitive radio network (CRN). The primary network (PN) consists of a single transmitter-receiver pair, and the secondary network (SN) is ... -
Sensing-throughput tradeoff in cooperative spectrum sensing
(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
(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
(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 ...
