QoS-Aware power allocation for spectrum sharing

To provide better usage of spectrum, regulators, such as the FCC and Ofcom, have been considering how to share spectrum between operators and also between different types of network. Two important aspects of any mobile service that need to be considered are how to ensure the appropriate level of service to individual users and how to minimize power consumption. This paper addresses the issue by applying orthogonal spectrum sharing, with the objective being to serve as many as possible users that meet their QoS requirement, together with minimizing the overall power transmitted. Multi-objective Game Theory is split into sequential single-objective optimizations and the paper presents results of simulations that show that this approach can achieve significant savings in power while maintaining the number of qualified users.
