Method for Evaluating the Quality of Service Characteristic of a Packet Access Network for IoT Devices

This paper presents a method for assessing such a service quality characteristic as packet access network bandwidth for IoT devices. To determine the real bandwidth proposed its mathematical apparatus at the level of calls and at the level of packets, which allowed to fully explore the traffic of IP-communications. At the call level from IoT devices, the Engsett model through small groups of devices themselves is used for traffic, and at the packet level, the self-similar flow model is used. Calculation of the characteristics of the quality of service in the packet communication network is reduced to determining the Hurst coefficient of self-similarity of traffic, after which the average number of packets in the system is calculated using the known formula of Norros.
