本文针对能量采集认知机器到机器(Machine-to-Machine,M2M)通信的能量效率问题,在保证服务质量(Quality of Service,QoS)的条件下,提出了一种能效优化算法.以最大化网络中用户能效为目标,综合考虑传输功率控制、时隙分配、传输模式选择、中继选择以及每个设备的能量状态为约束,将优化问题建模为一个混合整数非线性规划问题.将该能效优化问题转化为离散时间有限状态马尔科夫决策过程(Discrete-time and Finite-state Markov Decision Process,DFMDP)进行求解.提出一种基于深度强化学习的算法寻找最优策略.仿真结果表明,所提算法在平均能效方面优于其他方案,且收敛速度在可接受范围内.
Abstract
In order to optimize the energy efficiency for energy harvesting-powered cognitive M2M communications underlaying cellular network
an energy efficient algorithm is proposed while guaranteeing the quality of service of users. Firstly
the problem is formulated as a mixed integer nonlinear programming problem with the goal of maximizing energy efficiency by jointly considering transmission power control
time slot allocation
transmission mode and relay selection with the constraints of the energy status of each device. After that
the optimization problem is modeled as a discrete-time and finite-state Markov decision process. Afterward
a deep reinforcement learning-based algorithm is proposed to find the optimal strategy. Numerical results validate that the proposed scheme outperforms other schemes in terms of average energy efficiency with an acceptable convergence speed.
