本文提出了基于 IEEE 802.15.4e 标准的无电池能量收集供电无线传感器节点的策略，以最少的尝试成功加入网络，从而最大限度地减少能源浪费。这包括使用尺寸合适的电容器和不同的占空比来连接网络。实验结果表明，使用 100 mF 储能电容器的无线传感器节点通常可以一次尝试加入网络，但如果使用较小的电容，尤其是在收集的功率较低时，可能需要多次尝试。通过占空比网络加入，形成网络所需的时间较短，从而减少了节点加入网络时的整体能量消耗。通过使用所提出的方法，一次尝试成功地形成了能量收集供电的无线传感器网络（WSN）。
This paper presents strategies for batteryless energy harvesting powered wireless sensor nodes based on IEEE 802.15.4e standard to join the network successfully with minimal attempts, which minimizes energy wastage. This includes using a well-sized capacitor and different duty cycles for the network joining. Experimental results showed a wireless sensor node that uses a 100 mF energy storage capacitor can usually join the network in one attempt but multiple attempts may be needed if it uses smaller capacitances especially when the harvested power is low. With a duty-cycled network joining, the time required to form a network is shorter, which reduces the overall energy usage of the nodes in joining the network. An energy harvesting powered wireless sensor network (WSN) was successfully formed in one attempt by using the proposed methods.
