MACCA: A SDN Based Collaborative Classification Algorithm for QoS Guaranteed Transmission on IoT

Software defined network (SDN) can effectively balance link loads and guarantee QoS for different application categories of data streams on Internet of Things (IoT). To achieve high accuracy and low time consumption for stream classification for SDN, the collaborative methods are considered. By analyzing the data sets of network flows on CyberGIS and IoT, a Misclassification-Aware Collaborative Classification Algorithm named MACCA is proposed. MACCA collaborates the misclassification results judgment module and the decision module to calculate the final classification results, thus it can avoid the reduction of overall accuracy caused by voting to determine the results. The evaluation results show that the MACCA can classify the network data streams efficiently with an average accuracy of 99.66% and a lower time consumption compared to other classification algorithms, which can be implemented on SDN-based networks.
