Self-organized spectrum access in small cell networks: A noncooperation interference minimization game solution

This paper investigates the problem of co-tiered interference mitigation for small cell networks, in which most small cell base stations (SBSs) are deployed in an ad-hoc manner with minimum intervention from the end users and the service providers. Some game approaches are proposed to solve such problem distributedly. However, in most existing studies (include game approaches), a central controller or information exchange is needed for resource allocation and interference mitigation, and only single channel allocation problem is considered. In this paper, we propose a noncooperation interference minimization game approach to mitigate the co-tiered interference distributedly with multichannel selection. In the proposed game, each player (SBS) tries to minimize the aggregate received interference in its selected channels without information exchange. Moreover, simulation results show that it could achieve a good tradeoff between fairness and throughput by minimizing the network aggregate interference.
