Development and Research Self-Organizing Network Based on Protocol IEEE 802.11 Wi-Fi

The article describes how to organize a channel for data transfer using the IEEE 802.11 Wi-Fi standard defined by the mesh topology. As the end nodes of the network, fairly common modules based on the ESP8266EX microprocessor are used, which differ from their competitors not only by the ease of downloading the program code and further use, but also at a relatively affordable price. Theoretical, practical indicators of communication range, the question of the security of the self-organizing network obtained and possible applications are analyzed. Theoretical calculations of the communication range were confirmed experimentally, showing an excellent result in the percentage of received packets. The results obtained completely satisfy the definition of the topology used. Based on the definition of the 802.11s standard, an increase in the network when connecting points can occur at any time, which increases the distance between the sender and the receiver. Development can be used to exchange messages in narrowly specialized industries, educational purposes, and also apply universally.
