A Novel Utility Function of Power Control Game in Multi-Channel Cognitive Femtocell Network

Abstract

Importance of power control is associated with distributed user characteristics, which is self-organized and non-cooperative in multi-channel cognitive femtocell network. Power control on proposed PCG was based on the use of game theory method by generating the utility function that referred to the provision of solutions to the weakness of previous studies that was the inability to achieve the SINR target. The results showed that the proposed PCG was able to achieve the target SINR so that the quality of service can be fulfilled properly. This achievement has not been met by other methods (KG and TB methods). In addition, each of these three methods had nearly similar convergent rate, thus it can be concluded that the stability of these three methods were similar.
