Performance of DIO Suppression attack in RPL based IoT networks

Abstract

Wireless sensor networks are very important in many uses, but they can be attacked, which can make the network less secure and less effective. The Routing Protocol for Low-Power and Lossy “Networks (RPL) is the target of the DIO silencing attack. The goal of this study is to figure out how the DIO suppression attack affects RPL and how well the NLBGNDO algorithm stops the attack. To reach this goal, an accurate model of the RPL protocol and the DIO silence attack are built into a modelling code. The modelling code includes the NLBGNDO routing algorithm, which is a suggested safe and effective routing method for RPL. Key measures, like the number of packets delivered, the length of the path, and the amount of power used, are recorded and analysed both when the network is working normally and when it is under attack. The results of the study show how vulnerable RPL is to the DIO suppression attack and how well the NLBGNDO algorithm works to protect against its effects. The packet delivery ratio shows how the attack affects the network's ability to send data, and the route stretch measure shows how well the routing method works when under attack.
