Abstract:

Power control is one of the key techniques in wireless networks. In order to improve Pareto efficiency of the algorithm of noncooperative power control game in heterogeneous wireless networks (HNPG), the idea of the Best Equal SIR(BES) of all data terminals is introduced, make sure all data terminals work on the best equal SIR, all voice terminals work on the target SIR of the Qos(Quality of Service) threshold; a new distributed algorithm based on Best Equal SIR in heterogeneous wireless network(HBES) is presented. Numerical results suggest that the algorithm can improve the capability of the system; terminals have higher utility and lower transmit power relatively, making terminals use wireless resources more rational and impartial.

Key words: wireless networks, power control, best equal SIR, utility
