Cognitive Radio (CR) has been studied recently as an enabling technology for dynamic spectrum access. In this paper, the concept of Bandwidth Time Cube (BTC) is defined with a three dimensional space for maximizing spectrum usage to model radio spectrum management. In order to utilize unused frequencies, a DSHR (Dynamic Spectrum Heuristic Replacement) algorithm is proposed for a multi-hop CR networks...
Under Cognitive radio (CR), the Quality of Service (QoS) suffers from many dimensions or metrics of communication quality for improving spectrum utilization. To investigate this issue, this paper develops a methodology based on the multiobjective optimization model with genetic algorithms (GAs). The influence of evolving a radio defined by a chromosome is identified. The Multiobjective Cognitive Radio...
This paper attempts to identify the reliability of detection of licensed primary transmission based on cooperative sensing in cognitive radio networks. With a parallel fusion network model, the correlation issue of the received signals between the nodes in the worst case is derived. Leveraging the property of false sensing data due to malfunctioning or malicious software, the optimizing strategy,...
