Abstract
This chapter presents a microeconomic-based 'green' radio framework, in which a network operator contracts with one of its inactive end-users, with the specific intention of reducing the transmitted power of its source nodes and the costs incurred in providing the service. The proposed approach bears comparison with a tender process, where each inactive end-user submits a tender to the operator, describing the energy- and cost-savings that may be provided if selected to relay data to the intended destination. The operator will then associate additional measures to each submitted tender that quantify the downsides which may result from cooperating with that specific end-user. Finally, there is the tender evaluation and selection procedure, which may be compared with solving a multi-objective optimization problem. Our results disclose that the proposed framework can attain up to 68% energy savings and up to 65% cost savings over the direct transmission benchmarker.
