Identification of DDoS Attack on IoT Network Using SDN

This study discusses how Software-DefinedNetworking (SDN) overcomes the majority of the shortcomings of wireless sensor network. An SDN-IoT framework, where sensor nodes are integrated to work inan SDN environment has been proposed. The sensor nodes send their transmission data to the SDN controller using Mosquitto broker. The sensor nodes are analysed by sending the data to the python application which computes the Packet rate and Bandwidth. If the packet rate and bandwidth are found to be above the threshold, the DDOS attack is said to take place. In future, the solution would be integrated with Machine Learning approach to detect the DDOS attacks.
