Stackelberg game approach for wireless virtualization design in wireless networks
Thinh Duy Tran, Long Bao Le · 2017
We propose a wireless virtualization framework based on the Stackelberg game model for resource allocation in downlink orthogonal frequency division multiple access (OFDMA) wireless networks. Specifically, the wireless virtualization model enables an infrastructure provider (InP) to effectively lease radio resources to multiple mobile virtual network operators (MVNOs) through adaptively setting resource prices whereas the MVNOs selfishly optimize the resource allocation to maximize their utilities. The Stackelberg game approach is employed to solve the underlying hierarchical problems where the InP acts as a leader while the MVNOs play the roles of the followers. In particular, we derive the Stackelberg equilibrium (SE), at which no player has incentive to deviate unilaterally. Extensive numerical results are presented to confirm the efficacy of our proposed framework in balancing the achievable utilities of the InP and MVNOs compared to other traditional pricing schemes.
