In the MEC network, one BS equipped with MEC server and 10 users are deployed. The size of the network is 100m * 100m.
The maximum transmission power of the user is Pmax = 40dBm.
Every two users are divided into one user group, and two users of the same user group occupy the same channel. The bandwidth of each channel is 10MHz. The noise power of AWGN is 174dBm/Hz.
We consider the channel fading model including large-scale fading and small-scale fading. Large-scale fading includes path loss and shadow fading. The expression of path loss is L(d) = 37 + 30 log(d)£¬where d is the distance between the BS and the user. The standard deviation of shadow fading is 8dB. Rayleigh channel model with mean value of 0dB and variance of 8dB is used for small-scale fading.
