We propose a secure parent node selection scheme in the IPv6 Routing Protocol for Low-power and Lossy networks (RPL) so that each child node can select a legitimate node as its parent. In the proposed scheme, each node chooses a parent after excluding too good candidate if multiple parent candidates exist. Our scheme utilizes the fact that an attacking node claims falsely a lower rank than that of legitimate nodes. Simulation results show that the proposed scheme reduces the total number of child nodes attached to attacking nodes.
