Node connectivity is examined in the article as one of the most important characteristics of any information and telecommunication network quality. The article is devoted to determining the FANET parameters PDR (Packet Delivery Ratio) more than 90% at the specified territory. All results were obtained in the course of the experimental study. Simulation modeling was as a research method and it was based on ns-2 network simulator. Characteristics of the network developed according to the simulation model using the AODV routing protocol have been specified. The connectivity dependence on such network parameters as the number of nodes and the transmission range has been examined. Analysis results of the routes lengths depending on the parameters are presented.
