A Game Approach for Cell Selection and Resource Allocation in Heterogeneous Wireless Networks
Cell Selection and Resource Allocation (CS-RA) are processes of determining cell and radio resource which provide service to Mobile Station (MS). Optimizing these processes is an important step towards maximizing the utilization of current and future networks. In this paper, the authors investigate the problem of CS-RA in heterogeneous wireless networks. Specifically, they propose a distributed cell selection and resource allocation mechanism, in which the CS-RA processes are performed by MSs independently. They formulate the problem as a two-tier game named as inter-cell game and intra-cell game, respectively. In the first tier, i.e. the inter-cell game, MSs select the best cell according to an optimal cell selection strategy derived from the expected payoff.
