ProSD-EdgeIoT: Protected Cluster assisted SDWSN for Tetrad Edge-IoT by Collaborative DDoS Detection and Mitigation

ABSTRACT Software-Defined Networking (SDN) and Edge computing are the major elements due to its scalability, flexibility and efficiency. Still, security is one of the significant issues. Distributed Denial of Service (DDoS) is the harmful attack that exhausts many resources. The existing solutions consume large time for detection and present poor mitigation schemes. To address these issues, this paper presents a Protected Cluster-assisted SDWSN for Edge-IoT (ProSD-EdgeIoT) architecture. The ProSD-EdgeIoT follows tetrad architecture that performs clustering in the device layer, first-level DDoS detection in the edge layer,second-level DDoS detection in the control layer and multi-level DDoS mitigation in data forwarding layer.
