Decentralized Management Protocol for Wireless Sensor Network in Industrial Internet of Things

The paper comprises construction and evaluation of a decentralized management protocol in a self-organizing decentralized wireless sensor network (WSN) within the framework of the Industrial Internet of Things. The protocol is focused on organizing and supporting the functioning and monitoring of the information security of the network in order to collect, process, store and analyze data from the WSN nodes in conditions of high dynamism and variability of the network structure, the set of the nodes, their physical location in space, the behavior of the nodes and the amount of their available resources. This paper focuses on three proposed basic algorithms that constitute this protocol, their essence and analysis. In particular, it reveals the features of two alternative protocols for forming a multilateral session of WSN nodes, which provides a secure decentralized network operation using a node role model and blockchain as a means to organize distributed secure data storage on WSN nodes. In addition, the proposed protocol is oriented to solve the problems of monitoring the information security of a self-organizing decentralized wireless sensor network and detecting attacks that exploit, particularly, the properties of self-organization and decentralization of the network.
