LoRaWAN Network Capacity Analysis for Smart Water Grid

摘要

As a first step toward Smart Water Grid, we study the suitability of LoRaWAN for smart water metering. Due to the huge number of smart water meters to connect, we perform pre-deployment studies to understand the capacity of the LoRaWAN network. Accordingly, we seek to determine the number of smart water meters supported by a single gateway. Under NS3, we show that one LoRa gateway is able to support approximately 1000 smart water meters with about 92% of the packet delivery ratio. It is also important to note that according to our simulations, we observe that LoRaWAN is sensitive to the number of nodes.
