AbstractThis chapter elaborates on radio resource management issues for an optimum frequency portion exploitation and maximum energy conservation in a centralised cognitive radio network architecture. Two optimisation algorithms are provided that enable the efficient use of TV White Spaces (TVWS) through a broker entity that coordinates the spectrum trading process among a number of wireless secondary systems. TVWS can be a mixed economy with licence-exempt use, or light-licensed or licensed approaches. The resource management can facilitate different mixes according to alternative context and needs. In this framework, this chapter is mainly focused on the effective use of TVWS as a part of the mobile operators' spectrum portfolio. This is one strand of TVWS administration, while the chapter does not cover other use-cases for the exploitation of this spectrum part by microphone users or Wireless Internet Service Providers (WISPs). The proposed approach follows a real-time spectrum trading scheme based on either a fixed-price or a combinatorial auction-based method, depending on the requirements for spectrum by the secondary systems. The validity of the two energy-efficient algorithms is tested via several simulations, carried out under controlled conditions. The simulations evaluate the performance of the algorithms in terms of energy consumption levels, the spectrum broker benefit, the end-to-end latency and the throughput response.
