Roaming with Long Range wide-area network (LoRaWAN) requires connections to home Network Servers (hNS), serving Network Servers (sNS) and forwarding Network Servers (fNS) across LoRa domains. Today, this entails a tedious manual process for generating the keys, certificates and configuration files to connect these servers on a peer-to-peer basis. This means that manual configurations grow quadratically with the number of LoRa networks involved. In addition, today there is no way to enable roaming across LoRa networks dynamically (i.e., not if these pre-configurations among the visited and the home/serving LoRa networks aren't in place). Accordingly, presented herein are techniques to scale LoRaWAN roaming linearly, while not only automating the entire roaming process, but also allowing the acceptance of dynamic roaming requests. Opposite to conventional arrangements, such as roaming hubs, where roaming partners need to adhere to the hub's rules for packet routing, service levels and trust, the techniques presented herein act transparently to the servers, keeping routing and data exchanges under the control of each peer.
