Identifying IoT Devices Based on Spatial and Temporal Features from Network Traffic

Algorithm 1

The algorithm for data preprocessing.

	Input: raw network traffic pcap files
	Output: Samples_Data
	Use SplitCap tool to convert raw pcap files into Flows with the same 5-tuple
	information, , , …, , represents the last Flow in raw pcap
