Talk Title: Energy-Efficient Cooperative Spectrum Sensing for Cognitive Radio Networks

Cognitive radio (CR) can dynamically adapt its behavior, through its awareness, to the radio environment and spectrum policy. One of the most critical components of CR technology is spectrum sensing (SS). By sensing and adapting to the environment, a CR is able to fill in spectrum holes and serve secondary users without harmful interference to the primary users (PUs). A compromise between sensing performance and overhead in cluster-based spectrum sensing for cognitive radio networks (CRNs), is still a critical issue. This matter has attracted the attention of many researchers to tackle the trade-off between the performance and overhead. This talk considers energy efficient algorithms to minimize control overhead and provide better detection performance, increase the throughput, and reduce considerably both the overhead and the reporting energy. The talk will also consider algorithms for cooperative SS (CSS) in CRNs to meet PU protection requirements and minimize the total energy consumption. Energy efficient strategies are also considered to minimize the collaborating CRs required for CSS system, increase the energy efficiency and meet the detection requirements.
