A system for network topology includes a first edge router node and a plurality of first sensors operatively connected to the first edge router node. A second edge router node is operatively connected to the first edge router node and to the plurality of first sensors. A plurality of second sensors are operatively connected to the second edge router node and to the first edge router node. The first and second edge router nodes are operatively connected to a cloud server through a respective cloud connection, so that in the event of one of the cloud connections becoming unavailable the plurality of first and second sensors in the system can remain operatively connected to the cloud server through the remaining cloud connection.
