Protocols of data collection networks based on IEEE 802.15.4 radio channels in complexes for the protection of underground metal structures from electrochemical corrosion

Radio communication systems in telemetry and telemechanics systems of active electrochemical protection of underground metal structures are considered. The requirements for radio exchange systems for data collection networks from remote control and measuring points of cathodic protection stations are formulated. The analysis of the applicability of known exchange protocols based on the specifications of the IEEE 802.15.4 standard and its software add-ons for such networks is carried out and the need for the development of specialized network and channel layer protocols is justified. The results of the development of specialized network protocols of the application, network and channel levels that implement data exchange modes required for the collection networks under consideration while minimizing energy consumption are presented.
