A Survey of Distributed Denial Service Attacks Detection and Prevention in SDN-Internet of Things

The fundamental idea of IoT is the pervasive existence of an array of objects or things such as actuators, Radio-frequency Identi�cation (RFID) tags, mobile phones, sensors, and so forth. The Smart Security Mechanism uses the standard northbound and southbound interfaces of SDN, and it contents a low-cost technique that monitors the DDoS based attack by reusing the asynchronous communication on the control link. Software-de�ned networking (SDN) provides a latest method to achieve secure, reliable and cheap idea of IoT. In IoT traditional IP networking unsuitable when dealing with various IoT scenarios. It should be noted that, the flexible and effective SDN based IoT also inherits the security issue of the SDN architecture. The prevention and detection of DoS attack in an IoT is challenging task for the researchers. DoS attacks usually flood IoT networks and increases massive traffic in order to overthrow the target resources and make impossible or difficult for valid IoT users to use services. This paper provides the survey of SDN based DDoS attack detection and prevention techniques in IoT.
