Securing RPL Routing Path for IoT against rank attack via utilizing layering technique
Directorate of Inspection, Ministry of Health, Baghdad, Ahmed R. Zarzoor · International Journal on Electrical Engineering and Informatics · 2021
RPL is common protocol for the Internet of Things (IoT) network, that used for routing data freely among smart "things" in various environments.Which makes them susceptible to attack, especially of the rank attack (RA) that is common for RPL that based on manipulated the rank value for each node in the network to disrupt the routing path.Also, RA is increasing latency between (source node and destination node) and maximizing nodes' energy usage in the whole network.Therefore, in this study a new technique is proposed to protect RPL against rank attack based on layering mechanism.The proposed technique consists of three steps: Classifying node into layers, calculating path trust value and identifying and alleviating rank attack.The method is implemented via using Cooja simulator software.The network performance is measured according to three metrics: latency, nodes' energy consuming and accuracy of malicious node detection.The simulation results have revealed that the proposed method gives higher accuracy of malicious node detection, low nodes' energy usage, and less latency in comparison with Sec-Trust study.
