CORAL-SDN: A software-defined networking solution for the Internet of Things

Abstract

Recent proposals enhances Wireless Sensor Networks (WSNs) with Software Defined Networking (SDN) practices, introducing new innovative network control strategies and protocols based on a central control logic, i.e., enabling WSNs as crucial facilities for the Internet of Things (IoT). In this direction, we demonstrate CORAL-SDN, an SDN solution for WSNs which: (i) uses intelligent centralized control mechanisms to adjust dynamically the protocol functionalities; (ii) supports elasticity to the challenging requirements of the WSNs; (iii) maintains a scalable architecture; and (iv) exhibits improved network management and operation in terms of performance and resource utilization. With this demo we provide a suitable environment for hands-on experimentation, featuring the CORAL-SDN protocol operation in real test-beds and highlighting the improvements that SDN brings to IoT.
