Abstract:

This paper presents mechanisms for detecting Version Number and Rank Decrease Attacks on a sensor network based on IEEE802.15.4/6LoWPAN technology with the RPL routing protocol. In addition to detecting intruders carrying out the indicated attacks, the presented mechanisms also minimize the attack's effects. The tests of the developed solutions indicate high intruder detection efficiency, even with a significant number of simultaneously attacking nodes. Furthermore, using the developed mechanisms significantly reduces the energy consumption of network nodes during an attack, and minimizes signaling traffic.
