  • 摘要: 最新研究表明,高速传输导致的手机温度变化会影响相应的传输性能。针对高速传输下未考虑与手机温度有关的能耗中断而导致传输性能降低的问题,该文提出一种基于深度强化学习的资源管理方案去考虑无人机(UAV)通信场景下的能耗中断。首先,给出无人机通信的网络模型与智能手机热传递模型的分析;其次,将能耗中断的影响以约束条件的形式整合到无人机场景的优化问题中,并通过联合考虑带宽分配、功率分配和轨迹设计优化系统吞吐量;最后,采用马尔可夫决策过程描述相应的优化问题并通过名为归一化优势函数的深度强化学习算法求解。仿真表明,所提方案能有效提升系统吞吐量并得到合理的无人机飞行轨迹。

          产生随机噪声向量Nt
          选择当前时隙动作at=α'(st|vt)+Nt
          执行动作a(t)并获得即时奖励rt和下一时隙状态st+1
          将经验(st,at,rt,st+1)存储到经验池X
          从经验池X中随机抽样包含M条经验的Mini-batch
          对于经验m计算:ym=rm+γˆV(sm+1|vt)
          计算损失函数:
          L(vt)=1MMm=1(ymQ(sm,am|vt))2
          使用梯度下降法对主网络进行更新:
          vt:=vtαL(vt)
          t:=t+1,每隔Y个时隙更新目标网络vt=vt
        Until t==tstart+T
        T:=T+1
     Until T>Tmax
