Machine‐to‐machine (M2M) communication interconnects a large number of machines to exchange information in a network. These battery operated devices exhaust their energy after continuous usage for a long period of time. Discontinuous reception (DRX) standardized by the third generation partnership project (3GPP) is an efficient power saving protocol used in wireless networks. The power saving achieved by the DRX mechanism is often compromised with the ensuing buffering delay suffered by the packets. DRX mechanism with energy harvesting improves the performance of the M2M devices by exploiting the extra sleep cycles yielded by the harvested energy. However, the operation of the energy harvesting‐DRX (EH‐DRX) in the fifth generation (5G) millimeter‐wave (mm‐wave) systems with beamforming results in poor performance metrics. Beamforming is used in 5G mm‐wave networks for a base station to communicate with a group of devices situated in a particular direction. In this paper, an analytical model is devised by merging a beam‐aware mechanism with the EH‐DRX in the M2M mm‐wave 5G networks to improve the energy efficiency. As a result, the power saving at the user equipment (UE)/M2M device is enhanced by 16% by the proposed method compared with the original EH‐DRX mechanism.

机器对机器毫米波5G通信中的波束感知能量收集不连续接收

机器对机器（M2M）通信将大量机器互连，以在网络中交换信息。这些电池供电的设备长时间连续使用后会耗尽能量。由第三代合作伙伴计划（3GPP）标准化的不连续接收（DRX）是一种在无线网络中使用的高效节能协议。DRX机制实现的节能通常会受到随后数据包遭受的缓冲延迟的影响。具有能量收集功能的DRX机制通过利用由收集的能量产生的额外睡眠周期来改善M2M设备的性能。但是，具有波束成形功能的第五代（5G）毫米波（mm-wave）系统中的能量收集DRX（EH-DRX）操作会导致性能指标不佳。波束成形用于5G毫米波网络中，用于基站与位于特定方向的一组设备进行通信。本文通过在M2M毫米波5G网络中将波束感知机制与EH-DRX合并来设计分析模型，以提高能效。结果，与原始的EH-DRX机制相比，通过提出的方法，在用户设备（UE）/ M2M设备上的节电提高了16％。
