中文摘要	A non-cooperative power control algorithm is proposed based on the model of wireless CDMA sensor networks. A node payoff function which involved of utility function and cost function is modeled in the algorithm and the transmitting power vector is obtained by parallel update. It is proved that the sensor network can reach Nash equilibrium with this transmitting power vector, and in this situation all the nodes' payoff function is maximized. The OPNET is applied to simulation process of the algorithm, during which simulation has been carried out with different index combinations. Results show that the power control algorithm based on the game theory model has a very good astringency. Performance of the system can be improved through the selection of the utility factor between 1.0-1.1 and price factor between 5.5-5.9.
