Reliability Analysis of Systems with Dynamic Structure Based on the Properties of Nodes and Channels

Systems with a dynamic structure belong to the class of systems that are resistant to network destruction (Disruption-tolerant networks), i.e. allowing to transmit data in the case when mobile nodes are connected only periodically. The uncertainty of the state of mobile networks is a factor that complicates the solution of the routing problem. Traditional routing schemes are based on the assumption that at any given time two nodes can communicate either directly or transitively through other nodes, that is, the network is connected. Considering access routes between nodes as links of an information system, we can conclude that the assessment of routes according to the reliability criterion is one of the tasks in a set of measures to assess the ability of violators to implement security threats. To assess the consequences of the destruction of links, various metrics can be proposed in the literature, the paper considers metrics based on the analysis of the connectivity of the nodes of the system and on the basis of the number of destroyed paths between the system nodes.
