Low-power lossy networks performance relies heavily on the wireless node battery status. Furthermore, Routing Protocol for Low-Power and Lossy Network routing protocol was not optimally designed with sustainable energy consumption in mind to suit these networks. Prolonging the lifespan of these networks is of utmost priority. This article introduces a solar energy harvesting module to power energy-constrained network devices and quantifies the effect of using harvested energy on prolonging their network lifetime when Routing Protocol for Low-Power and Lossy Network routing protocol is used. Simulation of the new developed module is conducted in three different scenarios using Contiki Cooja simulator sporting Zolertia Z1 motes. Furthermore, the harvested energy used was fed from a Cooja-based Simulation model of actual PV supercapacitor circuit design. All battery levels were set to 1% of their total capacity for all nodes in the network to speed up observing the energy harvesting effect. The performance evaluation results showed that the network with no-energy harvesting operated for time duration of 4:08:04 time units (i.e. hour:minute:second) with a dramatic decrease in connection between nodes in the network. However, the same network, when using the harvested energy to back up the battery operation, lasted for 6:40:01 in time units with improved connectivity, a total extended network lifetime of 2:31:97-time units. Furthermore, for the Routing Protocol for Low-Power and Lossy Network routing metrics, OF0 outperformed ETX in term of throughput, packet delivery ratio, energy consumption, and network connectivity. Results indicate that the developed harvested energy module fits perfectly for any Cooja-based simulation and mimics actual photovoltaic-based supercapacitor battery. It should also help researchers introduce and quantify accurately new energy consumption-based routing metrics for Routing Protocol for Low-Power and Lossy Network.

低功耗有损网络性能在很大程度上依赖于无线节点电池状态。此外，低功耗和有损网络路由协议的路由协议并未针对可持续能源消耗进行优化设计以适应这些网络。延长这些网络的使用寿命是重中之重。本文介绍了一种太阳能收集模块，用于为能量受限的网络设备供电，并量化了使用低功耗路由协议和有损网络路由协议时使用收集的能量对延长网络寿命的影响。使用运行 Zolertia Z1 微粒的 Contiki Cooja 模拟器在三个不同场景中对新开发的模块进行模拟。此外，所使用的收集能量来自基于 Cooja 的实际光伏超级电容器电路设计仿真模型。网络中所有节点的所有电池电量都设置为其总容量的 1%，以加快观察能量收集效果。性能评估结果表明，无能量收集的网络运行时间为 4:08:04 时间单位（即小时：分钟：秒），网络中节点之间的连接急剧减少。然而，当使用收集的能量来支持电池操作时，同一个网络以改进的连接性持续 6:40:01 的时间单位，总的网络寿命延长了 2:31:97 时间单位。此外，对于低功耗和有损网络路由指标的路由协议，OF0 在吞吐量、数据包交付率、能耗和网络连接。结果表明，开发的能量收集模块非常适合任何基于 Cooja 的模拟，并模拟实际的基于光伏的超级电容器电池。它还应该帮助研究人员为低功耗和有损网络的路由协议引入和准确量化新的基于能耗的路由度量。
