Routing policy verification for enhanced energy quality of service and security monitoring in IoT networks

The Internet of Things (IoT) is growing rapidly controlling and connecting thousands of devices every day. Software Defined Networking (SDN) simplifies network management tasks by separating the control plane. However, the increased network traffic results in energy and Quality of Service (QoS) efficiency issues, whereas IoT devices are susceptible to failures and attacks that have serious security consequences. In this regard, providing a guarantee that SDN routing satisfies energy, QoS and security related policies is crucial for the network management. In this paper, we propose a policy-based framework aiming to verify that SDN routing decisions are optimal regarding energy, QoS and security properties. The proposed framework will enable the IoT network operator to adjust the policy constraints according to the demands of each use case (e.g., aiming at more secure or faster network). Finally, our framework is illustrated using a representative evaluation scenario.
