The efficiency of using the broadcast protocol of work in the meteor communication channel substantially depends on the duration of the message packet and on the number of repetitions of the packet to achieve a given message reception quality.

Goal. Determine the required parameters for the transmission of message packets over the meteor channel for the broadcast protocol of operation for given volumes of transmitted information, providing a guaranteed average probability of the correct reception of the entire message and the minimum delivery time.

Results. A theoretical analysis of the optimal packet length and the number of repetitions for a different number of receivers is presented. Simulation was performed and the parameters of the broadcast protocol were confirmed, which ensure, for given volumes of transmitted information, the guaranteed average probability of successful delivery of the entire message while minimizing the delivery time.

Practical significance. It is shown that the theoretical packet length, determined from the condition of minimum number of repetitions, for three different probabilities Ps of successful delivery of the entire message is approximately 5500 bits.

The article presents research on the choice of parameters for transmitting message packets over the meteor burst channel for the broadcast protocol of operation for given volumes of transmitted information and the conditions for ensuring the guaranteed average probability of the correct reception of the entire message and the minimum delivery time. A theoretical analysis of the optimal packet length and the number of repetitions for a different number of receivers is presented. Simulation was performed and the parameters of the broadcast protocol were confirmed, which ensure, for given volumes of transmitted information, the guaranteed average probability of successful delivery of the entire message while minimizing the delivery time.
