5G networks provide high data rates, high bandwidth, high coverage, and low latency compared to 4G networks. However, 5G includes some challenges such as privacy, network management, security. To overcome these issues, we propose SDN-5G HetNet (Software Defined Network-based 5G Heterogeneous network) model which addresses three issues such as handover authentication, flow rule validation, and hybrid intrusion detection and mitigation. Authentication is performed by Bio-Signature Validation Authentication mechanism for validating the users. User credentials are stored in the public blockchain for security. Handover is performed by the Dual Constraints Chaotic Radial Movement Optimization algorithm using User Entity and Access Network constraints. Flow rules are hashed and stored in the private blockchain for validation. Also, flow rules are monitored using Hidden Markov Model (HMM). Simulation is performed using NS-3.26 network simulator, which demonstrates our proposed work achieves better performance in terms of detection accuracy, handover delay, switch failure rate, packet loss rate, delay, and throughput compared to other state-of-the-art works.
