Abstract The ad hoc networks are represented in the form of a random graph with a fixed number of units and the view of the processes of sending messages in the network are represented in this paper. On this basis, the basic characteristics of the distribution of random processes in simulated operation of these networks are determined. The main function of the probability distribution used in the simulation is represented and the main problem in the simulation of internal processes of the network is noted. For an accurate representation of the model and the time, we proposed to use an event-driven simulation approach of internal processes, which presented in the form of the final message flows that generate and process at each node of the network. The whole structure of the simulation processing time internal processes represented as the corresponding graphical model. Main task is to study the behavior of the main characteristics of the random distribution of the processes occurring in the analyzed systems. Calculated the optimal-minimal number of required tests to ensure the correctness and stability of the output data. The behavior and the processing of the primary and secondary processes depending on the number of peaks defined in the system are represented. The dependence of the number of processing messages, total processing time of all messages and load units on the number of tests in simulated network is analyzed. Depending on parameters that affect on the correctness of the output data and maintaining the system in steady state is considered and defined.
