Low false alarm attackers detection in RPL by considering timing inconstancy between the rank measurements

Abstract

We propose a low false alarm attackers detection in the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) by considering timing inconstancy between rank measurements. In the proposed scheme, each node sends the latest rank broadcasted to neighbor nodes instead of its current rank to a sink so as to avoid the rank mismatch due to timing inconstancy. We also introduce the timestamp for reporting rank measurements to decrease the false alarm due to packet loss. Simulation results show that the proposed scheme reduces the false alarm rate.
