The Spectrum Sharing in Cognitive Radio Networks Based on Competitive Price Game
The competitive price game model is used to analyze the spectrum sharing in the cognitive radio networks. This paper focuses on the improved spectrum sharing problem with constraints of available spectrum resource from primary users. The constrained spectrum sharing model based on competitive price game is established. In order to achieve the spectrum sharing strategy that satisfies the constra...
متن کاملSecure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...
متن کاملAuction and Game-Based Spectrum Sharing in Cognitive Radio Networks
One of the main reasons behind the concurrent increase in the demand for and congestion of Radio Frequency (RF) spectrum is the rapid development of radio networks of all kinds in our world, which has defiantly changed the public feeling about radio. Nowadays, almost everybody has a mobile phone and radio stations are literary everywhere. Someone can argue that our world is becoming a radio wor...
متن کاملUser Selection Based Cooperative Spectrum Sensing for Cognitive Radio Networks
In cooperative spectrum sensing, information from several cognitive users is used for detection of the primary user. To reduce sensing overhead and total energy consumption, it is recommended that users with good performance be selected so as to optimize the probability of detection. One method of selecting the cognitive users with the best detection performance is proposed in this paper. It fo...
