Research on power control with non-linear pricing method in cognitive Relay network
非线性价格的认知中继网络功率控制方法研究

When cognitive relay network aims at voice communication, there is a need for better maximizing of its throughput with minimal cost of power. A game theory model of power control with nonlinear pricing function is introduced after an analysis of the network in depth. Its solution of nash equilibrium depends on channel parameter and pricing parameter. This method of power control is more matchable to the network. It can decrease power consumption and boost energy efficiency of the network. In the meantime, it is also capable of lowering complex degree in realization of power control. Comparison of methods with two different price coefficient and simulation show that the method can get better performance of communication.
