Model of the distributed self-organizing network of IoT sensors

The paper considers the features of the simplified implementation of the protocol stack, the efficiency of routing and performance in the transit mode of data transfer devices, with the longest battery life priority. The solution to the problem of network devices in a network with a large number of sensors (for example, network of the Internet of things) is relevant and can be solved by creation of cellular network like mesh. But in such networks, there can be a situation when because of failure of one or several devices the operability of all network is broken. In this connection, it is offered to use for connections and data transmission the self-organized network on the basis of the channel Wi-Fi level and the PainlessMesh protocol. The four-dimensional model of Markov is developed for the research of application possibility of the proposed solution and analytical expressions for parameters assessment of network operation are obtained. Based on the resulting models the computing algorithm allowing to imitate scenarios of network operation is constructed. The models’ adequacy is confirmed by scenario emulation of the sensors cluster operation. The main results of the paper are: in the scientific aspect – the developed models of network operation assessment parameters of IoT; in the practical aspect – received by means of simulation, dependences delay schedules including network nodes on the number of nodes and "awakening" nodes’ speed. Besides, it is revealed that multiprotocol devices can work more effectively, at the same time supporting the necessary productivity of a data transmission network.
