Preliminary study: Non cooperative power control game model for cognitive femtocell network

Scarcity of bandwidth and usage inefficiency of frequency band encourage of using cognitive radio technology. Being motivated by green wireless communication makes us enthusiasm to utilize femtocell as a network with low power consumption. Power control scheme is one of what we need in cognitive femtocell network to improve network performance. This paper implement a non cooperative power control algorithm using game theoretical approach in cognitive femtocell network to enhance the network performance in systems throughput, interference mitigation, and optimal power allocation while reducing inefficient transmit power. Feasible system is absolutely necessary in wireless communication, especially cognitive femtocell network. The results of the feasibility test, a nonnegative power vector, will be used as the reference for implementation of the next process related cost function in game theory.
