Summary:Low Power Wide Area Networks (LPWAN) are expected to interconnect a high number of simple and inexpensive devices. The ability to control transmission parameters including modulation scheme and output power, enables reduction of the deployment costs, improvement of the network reliability, in terms of error performance under suboptimal conditions, and could contribute to the reduction of the maintenance complexity with respect to scaling of the network. This paper presents an analysis of the widely accepted adaptive data rate (ADR) algorithm implementation used in current LoRaWAN™-based network infrastructures. The authors propose improved variants of the algorithm concerning the design goals listed above and provide an experimental evaluation of their network performance.
