As energy saving and environmental protection become an inevitable trend, this paper studied the problem of the efficient resource allocation via power control and interference management approaches for multi-agents in two-tier femtocell networks. In this paper, a distributed power control algorithm is proposed to investigate the resource allocation using hierarchical game for two-tier femtocell networks. In the algorithm, the protection of higher-priority multi-agents' uplink communication and the optimal power allocation for lower-priority multi-agents are simultaneously involved. To manage the cross-tier interference and suppress the near-far effect in the code-division multiple access system, an adaptive pricing scheme is proposed. Numerical example is given to illustrate the effectiveness of the developed algorithms.
