RPL is an IEFT standard for building an outdoor wireless mesh, whose main application is smart cities and sensor networks. Outdoor wireless mesh networks are known to be vulnerable to numerous attacks that may be launched on any layer. Such attacks are usually divided into those conducted on the Phy/MAC layer and those conducted on the Network layer. It is easy to conduct a Phy/MAC layer attack, and much more difficult to conduct a Network layer attack. However, the impact of a Phy/MAC layer attack is usually very limited, whereas a Network layer attack may sabotage the whole network. In our work, we present a novel attack that is as easy to conduct as a Phy/MAC layer attack yet is as effective as a Network layer attack. This attack takes advantage of the RPL failure recovery mechanism and the RPL nodes' limited awareness of topological changes.
