Control of Information Stream for Group of UAVs in Conditions Lost Packages or Overloading

Abstract

The chapter deals with the problem of controlling the flow of information coming from a group of unmanned air vehicles (UAVs) by radio channel. The stream is a sequence of binary information packages. The inevitable data losses are compensated by repetition of lost packages or reconfiguration network. Modern methods control of data flow assumes using a mechanism ARQ based on the method sliding window. The consequence of these problems is a partial or total loss of its performance, manifested in a decrease in the network's starting throughput. Part of the problem of restoring the network is solved by routing mechanisms, which lead to a reconfiguration of the network due to the elimination of faulty nodes. Management of computer network overload is solved by well-known routing protocols, such as OSPF, IS-IS, RIP, and others. In solving the problem, the representation of the output of individual nodes of the network using the "death and reproduce" scheme was used substantially. This scheme of network operation presupposes its representation by the Markov chain and the derivation of probabilistic characteristics by solving the Kolmogorov equations.
