Abstract—The security of Machine-to-Machine (M2M) communication in the Internet of Things (IoT) is the primary focus of this research article. Despite the increasing reliance on IoT as a cornerstone of future technological advancements, M2M devices face significant challenges, including processing and storage limitations that make them vulnerable to security breaches and Distributed Denial of Service (DDoS) attacks. This paper introduces an innovative security measure against DDoS, called the Redundant IP Pool Strategy (RIPPS). RIPPS utilizes temporary IP pools during an attack to thwart unauthorized access by limiting the time available for infiltration. We conducted a simulation experiment using the OMNeT++ simulator to examine the behavior of IoT networks under DDoS attacks. Our study focuses on traffic management in typical scenarios, including Human-to-Human (H2H) traffic (e.g., Voice over IP and File Transfer Protocol traffic) and M2M traffic. The simulation results demonstrate that implementing RIPPS significantly enhances network stability by reducing packet loss and latency across all traffic scenarios. The RIPPS effectively bolsters the security and resilience of IoT environments against DDoS attacks.
