The study of brittleness of network information systems use various kinds of models, reflecting their topological and functional prop-erties. Assessing the brittleness of self-organizing packet radio networks using known models currently is a complex and unsolved task. The article presents a method of assessment of the brittleness of self-organizing packet radio network in the absence of a priori in-formation on the relationship of its subscribers. The peculiarity of the method lies in the consistent implementation of the stages of structural and parametric identification of self-organizing packet radio network, allowing to estimate the magnitude of the destructive impact of external factors on structural and functional network properties. Partial elimination of uncertainty the structure of the network is implemented by constructing a graph using the methods of energy calculation of radio links with the subsequent determination of parameters of its elements. The selected indicator of damage to the radio network by the deletion number, and an algorithm for its computation based on the classic centrality. Evaluation of brittleness is carried out by comparing the magnitude of damage caused by deliberate and accidental external destructive influences. The methodology is intended to apply to search subscribers, whose removal leads to the maximum disruption of the network structure, reducing its capacity and impaired functional properties of the whole system.
