Control system objects with multiple streams of information

The article deals with the problem of controlling the flow of information coming from a group of unmanned aerial vehicles by radio channel. The stream is a sequence of binary information packages. The inevitable data losses compensated by repetition of lost packages. Modern methods control of data flow assumes using a mechanism automatic repetition query based on the method of sliding window. In this paper the comparative analyses of the known methods are given. The property matching the volume of information, which transmitted from UAVs with the size M of the sliding window, is set. In base of theoretical calculations is used the concept of bandwidth. Computing bandwidth radio channel with the automatic repetition query technology allows are confirming the main result investigation.
