#### 2.2.3 Numerical Experiments  
The following numerical data were selected for numerical experiments: \(D=100;200\), \(l=256\) [bit], \(B=4\), \(N=5\), \(V_{1}=20\)[Mbit/s], \(V_{2}=80\)[Mbit/s], \(T_{a1}=T_{a2}=50\)[ms]. Figures 4-9 show graphs illustrating the results of numerical experiments. The influence of the number of terminal devices in the radio network \(D=100;200\) and the probability of access to service (i.e., to the IInd step) (Q = 1; 0.9; 0.7) on the PTC of the process of transmitting user data blocks in the radio network was studied. Figure 4--dependence of the probability that the transmitted user data blocks will be delivered in a timely manner on the intensity of receiving blocks for transmission. Figure 5--the dependence of the average transmission time of user data blocks on the intensity of their receipt for transmission. Figure 6--the dependence of the information speed of the real-time access radio network at the last mile on the intensity of receipt of user data blocks for transmission. The dependency graphs (Figures 4-6) show that an increase in the number of terminal devices, as well as the intensity of the appearance of user data blocks for transmission (i.e., an increase in the load on the radio network) leads to a noticeable deterioration of the studied characteristics of the transmission process. So, if the procedure for dropping part of the traffic at the 1 st service step is not applied (i.e., \(Q=1\)), if there are 100 working terminal devices in the access radio network, the range of operating intensities: \(\mu=0\ldots 380\) [1/s]. If the number of working devices is increased by two times, this range is reduced by almost two times: \(\mu=0\ldots 180\) [1/s]. However, the introduction of a procedure for sifting (discarding) part of the traffic at the 1 st stage of maintenance can significantly improve the PTC of transmission and increase the operating range of intensities. So, for the case described above, if you set the probability of access to service \(Q=0.9\),

Figure 5: The dependence of the average transmission time of user data blocks on the intensity of their receipt for transmission. Figure 6: The dependence of the information speed of the real-time access radio network at the last mile on the intensity of receipt of user data blocks for transmission. then at 100 operating terminals, the range of operating intensities: \(\mu=0\ldots 430\) [1/s], and when their number increases by two times: \(\mu=0\ldots 220\) [1/s]. Thus, we can say that the introduction of a procedure for sifting part of the traffic allows you to increase the stability of the access radio network to increase the load. The dependence of the probability-time characteristics of the process of transmitting user data blocks on the probability of denial of service (\(P\)) at different values of the intensity of receipt of user data blocks for transmission was studied (\(\mu=100\ldots 250\) [1/s]). Figure 7--graph of the probability that the transmitted user data blocks will be delivered in a timely manner versus the probability of a denial of service. Figure 8--graph of the dependence of the average transmission time of user data blocks on the probability of failure in service. Figure 9--graph of the dependence of the information speed of the real-time access radio network on the last mile on the probability of failure in service. From the dependency graphs shown in Figures 7-9, it can be seen that the introduction of a traffic screening procedure is advisable to use when the load on the network increases. From Figure 9 it should be noted that when considering the source data, it is necessary to enter a procedure for sifting part of the traffic, only when \(\mu>200\) [1/s].
