The low-power lossy network’s performance is strongly dependent on the battery life of each wireless node. Furthermore, the routing protocol for such a network does not address the energy issue that each node in the network faces. Novel techniques or approaches are necessary to handle the energy problem that nodes encounter in low-power lossy networks in order to extend the overall lifespan of each node in the network. This study focuses on improving the lifespan of energy-constrained nodes in low-power lossy networks by implementing a solar energy harvesting module. The current routing protocols used in such networks adequately address the energy problem faced by nodes. The study uses the Cooja simulator with ETX and OF0 protocols to analyze the energy harvested by nodes with 1% battery life and evaluates the network performance with 25, 50, and 100 nodes. The analysis includes throughput, packet delivery ratio, and network connectivity. The results show that OF0 outperforms ETX in all three scenarios, and performs well in the other parameters. With OF0, the network lasts for 12:50:58, 12:46:58, and 8:12:25 (non-energy harvesting), and 15:59:01, 15:12:07, and 11:18:23 (energy harvesting) for 25, 50, and 100 nodes, respectively. The study suggests that novel techniques, such as energy harvesting, could significantly improve the overall lifespan of nodes in low-power lossy networks.
