Purpose: In packet radio networks, you should be able to evaluate the efficiency of random multiple access to the environment type
S-ALOHA of such a network under remote infotechnical impacts from an attacker. The existing methods fail to comprehensively assess
the efficiency of this procedure because they do not take into account the effect of potential impacts and the amount of the available time resource. Another shortcoming of these methods is determining disparate characteristics: the quantitative indicator of successful package delivery and the qualitative indicator of random multiple access procedure stability. The aim of this research is a comprehensive quantitative assessment of the efficiency of random multiple access to the environment type S-ALOHA for a packet radio network under infotechnical impacts. Results: The method of evaluating the efficiency of random multiple access the environment type S-ALOHA of a packet radio network has been improved by taking into account the potential impacts, probabilities of a free channel, probability of stable functioning and determination of the comprehensive indicator of the efficiency of this procedure. By induction, a generalized analytical solution was obtained about how to find the marginal probabilities of the simulated states. Practical relevance: The model can be applied for the development of highly efficient algorithms resolving collisions in the procedure of random multiple access to the environment type S-ALOHA.
