PC-RPL: A Routing Protocol based on Power Control for IoT-based Low-Power and Lossy Networks

This paper proposes a routing protocol with a power control strategy for data collection in low-power and lossy networks. The proposed routing protocol determines the node rank mainly considering the proper transmission power of a node to its candidate parent. By using the power control technique, the node is able to select the suitable next forwarding node to establish the energy-efficient upward transmission route. Simulation results validated that the proposed routing protocol significantly extends the path lifetime and network lifetime compared with the routing protocol only using the hop count as the node rank.
