Software-Defined Network Application-Aware Controller for Internet-of-Things

In the following paper, we propose implementation of Application-Aware Controller (AAC) for Software-Defined Network (SDN) that integrates Internet-of-Things-devices (IoT-devices). The main goal of the investigation is to establish communication mechanisms for SDN and its main components and simplify overall complexity of the system by moving part of the logic into AAC-component. The presented approach leverages capability of SDN-controller to work on the application level and to process data according to the application logic. Generally speaking, AAC acts like a transparent network node that contains program logic. We have considered several scenarios for IoT-network and have devised solutions for communication organization in the cases that are based on usage of flow tables and packets generation. The proposed communication scheme has been evaluated using well-known tools for SDN-investigation and proved feasibility of the scheme.
