Fig. 10

Comparison of the contour maps of \(\eta _\xi\) and T under \(n = 150\). The figure shows comparison of the contour maps of \(\eta _\xi\) and T under \(n = 150\). We can see that in order to achieve the same value of \(\eta _\xi\) with different transmission number, which indicates the existence of the smallest transmission number and the corresponding optimal values of \(\omega\) and \(\xi\) to fulfill the near-broadcast requirement of mobile edge networks
