DDoS Botnet Prevention using Blockchain in Software Defined Internet of Things

Distributed Denial of Service (DDoS) attacks have two defense perspectives firstly, to defend your network, resources and other information assets from this disastrous attack. Secondly, to prevent your network to be the part of botnet (botforce) bondage to launch attacks on other networks and resources mainly be controlled from a control center. This work focuses on the development of a botnet prevention system for Internet of Things (IoT) that uses the benefits of both Software Defined Networking (SDN) and Distributed Blockchain (DBC). We simulate and analyze that using blockchain and SDN, how can detect and mitigate botnets and prevent our devices to play into the hands of attackers.
