Enhancing Secrecy Rate in Cognitive Radio Networks via Stackelberg Game

Enhancing Secrecy Rate in Cognitive Radio Networks via Multi-level Stackelberg Game

In this letter, physical layer (PHY) security is investigated for both primary and secondary transmissions of a cognitive radio network (CRN) that is in danger of malicious attempt by an eavesdropper (ED). In our proposed system, the secondary transmitter (ST) is acted as a trusted relay (TR) for primary transmission and the PHY security is facilitated by the cooperation between the primary tra...

Stackelberg Game for Resource Allocation with QoS and Fairness Assurance in Cognitive Radio Networks

This paper proposed a new Stackelberg game theoretic solution for joint power control and channel allocation in Cognitive Radio Networks (CRNs). The Primary Users (PUs) can admit Second Users (SUs) to access by pricing their interference power under the Interference Power Constraint (IPC). So, we formulate suitable revenue functions for SUs and PUs to manage the radio resource among users effic...

A Stackelberg game spectrum sharing scheme in cognitive radio-based heterogeneous wireless sensor networks

In this paper, we focus on spectrum sharing in heterogeneous wireless sensor networks (HWSNs) and consider Stackelberg game exploiting the cognitive radio (CR) technology to utilize those scarce resources. In the game, the licensed network controls and prices the available spectrum resource which the WSN relay: actor nodes can purchase and use to serve the attached sensor nodes as well as offlo...

Enhancing Attack Resilience in Cognitive Radio Networks

Enhancing Reliability of Radio Links in Cognitive Radio Networks

The radio spectrum being an important resource should be used with optimum performance. In Cognitive radio Networks it can be improved by pooling and dynamic allotment of resources. The Radio links performance deteriorates in the wireless channel due to numerous known and unknown disturbances. This problem had been tackled using channel coding techniques of various kind. Proper Channel coding t...
