Software Defined Networking (SDN) Controller Architecture in IOT healthcare systems with Blockchain Based Security
Abstract - In health care systems like health monitoring, fitness programs and others, the Internet of Things (IoT.) is growing enormously. Several investigations on the IoT-based monitoring of the health system about IoT. problems such as safety and security, the variety of devices have been long-standing. In IoT and edge network data transmission, security and safety play a major rule. The healthcare industry is one of the areas in which many technological organizations need to have security in order to secure storage their data. In this paper, we present a secure blockchain-enabled architecture of Software Defined Networking (SDN) controllers for IoT networks by using a cluster structure and a new routing protocol. The architecture employs private blockchains for peer-to-peer (P2P) communication between IoT devices and SDN controllers, eliminating the need for Proof-of-Work (POW), as well as an efficient authentication method with distributed trust which make the blockchain suitable for esource-constrained IoT devices.
