The Mesh Technology for Improving of End Nodes Updating for Lorawan Network

The problem of implementation of LoRa technology is considered due to the need for high-speed software updates for LoRa WAN network end nodes. Formed and tested effective software update protocols that do not require direct connection. The structure of the functional block diagram was selected, and the stand was assembled. Experimental testing and comparison of applicability the mechanisms in updating the software of terminal devices, for the cases of implementation of D2D communications on the basis of Mesh topology are provided. A list of technical characteristics and an ex-post evaluation of the quality of communication for PER and other indicators is considered. The complex index of estimation of efficiency of the whole network as a whole is offered. It is confirmed that the mechanism for updating FP devices, based on FSK modulation and Mesh topology, opens the capabilities of D2D communication increases the data transfer rate and energy efficiency of the end node in general by more than two orders of magnitude.
