Abstract: In the view of current node-degree power control scheme based on parameters leading to slow convergence speed and high energy consumption, Node distribution density ρ is introduced, combining with wireless propagation model and the number of neighbors estimation model, proposed a no-parameters power control algorithm (NPPC) is given out. Simulation results demonstrate NPPC contributes nodes to reach the desired number of neighbors quickly and improves the convergence speed and energy efficiency. NPPC has excellent stability performance in different deployment densities network.
