Abstract:

This paper presents an analysis of the impact of the deployment of intruders launching attacks on the topology and resources of a 6LoWPAN/RPL-based wireless sensor network. Blackhole, Sinkhole, Nodes Rank Decrease and DIS Flooding attacks were carried out in a network with an assumed topology composed of composed of dozens of sensors. The test results show the impact of locating intruders in the network on the effectiveness of attacks, as well as on the efficiency of the entire network. Analyses were made of the effectiveness of individual attacks, but in particular, the focus was on assessing the resilience of the network as a whole to the number of attackers and where they were deployed. The results show how sensor networks should be constructed so that potential attacks have minimal impact on the operation of the entire network.
