摘　　要：提出了一种基于业务请求负载感知的异构无线网络自适应协同休眠节能算法,在满足异构无线网络系统内业务服务质量要求的条件下最小化系统功耗.该算法在异构无线网络自优化框架下建立基于经济学收益的节能模型.蒙特卡洛仿真结果表明,在满足用户业务请求阻塞率约束条件下,新算法能自适应调度异构无线网络的工作模式,并降低系统总功耗.An adaptive service request load-aware cooperative sleeping energy saving algorithm for hetero- geneous wireless networks is proposed, and it minimizes system overall power consumption under the constraint on the quality of service requirement in the heterogeneous networks system. The proposed algorithm constructs the economic theory revenue based power-saving model under wireless networks self-optimization framework. Monte Carlo simulation demonstrates that the algorithm can adaptively schedule the working mode of heterogeneous wireless networks and decrease the system total power consumption, and satisfies the blocking rate constraint of user service request.
