摘要：
Different fashions of power supply have different power prices. In order to reduce power cost in mobile communication network, an algorithm is proposed to minimize the outage probability based on power cost. It subjects to the constraint of power cost. The Lagrange multiplier maximization method is used to solve the problem. Simulation shows that whether dual-hop or multi-hop transmission, the power prices of different nodes are not the same, the optimal power allocation based on power cost has lower cost compare than the optimal power allocation in the case of uniform outage probability. Whereas, the former has lower outage probability in the case of uniform power cost. The contrast is more obvious with the gap of power prices enlarges.
