Fig. 6From: A controller deployment scheme in 5G-IoT network based on SDNAverage latency of three algorithms with different controller numbers. x axis: number of controllers. y axis: average latency (ms): The figure shows that the average communication delay on the OS3E topology is calculated by the optimized DPC algorithm, the optimized k-means algorithm and the optimal placement algorithm respectively. And then, the data values we calculated by these algorithms are compared with each othersBack to article page
