A short study on SDN-Based IOT, Security challenges and its solutions

The Internet of Things۱ has grown exponentially with many applications from industrial systems to smart homes. Heterogeneous networks with different needs that traditional networks are not able to meet. Software defined networks۲ have come to help meet the needs and challenges of this network, and the main challenges in this area, security and reliability, are solved with the help of new ideas. Different methods, such as using blockchain, have all been proposed to detect, prevent, and eliminate IoT attacks. In this paper, we review some of these methods.
