MODEL OF REGULATED MULTIPLE ACCESS IN THE NETWORK INTERNET OF THINGS

A Protocol for multiple access to communication resources on the last mile section of the Internet of Things sensor network is proposed. The developed access Protocol takes into account the features of cyber-physical systems: heterogeneity of supported applications, super-density of networks, the need to save resources of network components (channel frequency resource, power consumption of smart things). The scenario of access to the resources of the last-mile access network using a two-phase model for servicing flows of heterogeneous data from smart things is described. First phase: managing the volume of traffic coming to global infocommunication resources. The second phase is the transfer of data blocks in accordance with the regulated synchronous-time multiple access method. A mathematical model is proposed that allows evaluating the quality of transmission in the Internet of things network under consideration. Expressions are obtained for calculating the probability-time characteristics of the process of transmitting various types of data: the average time and probability of timely delivery of data blocks generated by smart things, and the real-time information speed. Numerical calculation and analysis of the impact of traffic volume management procedures and multiple access parameters on the probabilistic and time characteristics of the transmission process on last-mile networks are performed.
