Abstract:
Industrial Internet of Things (IIoT) is one of the key features of Industry 4.0 that stands for a new approach to design industrial processes using the latest technological advances. However, before implementing new processes, it is necessary to understand the characteristics and limitations that arise due to technical complexity of the system. To solve this problem for some generalized IIoT use case, a mathematical model of the multiple access protocol with channel sensing is proposed. This model allows one to estimate the average sensor's data transmission cycle time, successful data transmission probability, and probability of a collision during data transmission. Analytical expressions for calculating key performance metrics at the access layer are proposed.
Keywords:
Industrial Internet of Things (IIoT), MAC layer, channel sensing, multiple access, Markov chain, collision probability.
