FAN Mesh Network Topology for Smart Cities

Wi-SUN networks are usually configured on a mesh network topology. In a mesh network, devices communicate with neighboring devices on their network, all of which can serve as conduits to the network base station (also known as a border router) as shown in the image here. This allows for multiple redundant connection paths, so unlike star-based networks, single points of failure and blind spots are dramatically reduced. In fact, as devices are added to the mesh, the mesh reliability and performance improves because the possible communication paths multiply. Wi-SUN mesh networks are self-forming; it automatically finds peers to communicate with and it is self-healing if obstacles emerge, so devices will automatically reroute to the nearest available peer reconnecting to the mesh.
