Annotation. In this article, the authors present the research results studying the use of a model-aided navigation method of improving the accuracy of positioning mobile data transmission nodes in peer-to-peer wireless networks. Accurate positioning of wireless network mobile nodes allows us to switch from a random network topology to a deterministic one and improve the information exchange quality characteristics, namely the availability of nodes, first of all. Mobile wireless nodes are expected to be equipped with GPS or GLONASS satellite navigation receivers. Provided that the maximum speeds and accelerations are known for carriers of mobile nodes of a wireless network, it is possible to improve the accuracy of navigation definitions by predicting the movement of the mobile node during subsequent navigation measurements. The results can be used to model the topology of a peer-to-peer wireless network, organize network routing and increase the availability of mobile nodes. The authors present experimental results of calculations of the likelihood of increasing the accuracy of navigation data and the magnitude of the increase in positioning accuracy when using a model-aided navigation method of positioning accuracy improving.
