Joint power control and interference management in two-tier CDMA femtocell networks for multi-agent systems

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.
