Proposing a DIO Suppression Attack in IoT Networks

Abstract

The Internet of Things (IoT) represents a transformative force, enabling everyday objects to become "smart" by facilitating communication between them. By connecting countless devices to the Internet, IoT allows for the exchange of vast amounts of data through sensors, aiding in data delivery, analysis, and the creation of optimal solutions. IoT applications are increasingly adopted across diverse domains and systems. However, this rapid expansion introduces new challenges, such as the accelerated energy depletion due to increased data traffic within the network. To combat this issue, several protocols have been developed. One of the most significant is the RPL protocol, now the standard for routing in low-power and lossy networks (LLNs). Despite its widespread use, RPL is vulnerable to various attacks on its control messages, presenting a major security challenge for future IoT systems. This research focuses on proposing DIO suppression attacks in IoT networks. By implementing our proposal, we aimed to achieve a lower Packet Delivery Ratio (PDR), higher Average End-to-End Delay (AE2ED), and higher Average Power Consumption. The proposed algorithm was implemented and tested using the Cooja simulator.
