24. Network Gateway Wired Data Link Wireless Data Link A node is selected as the gateway Wired or wireless loggers are connected to the gateway
25. A data path may become blocked The network will reroute the data via a different node Network Gateway Wired Data Link Wireless Data Link
26. Network Gateway Rerouted Wireless Data Link Data are again rerouted when the obstruction is cleared This is a “Self Healing Network”
27. Network Gateway Wired Data Link Wireless Data Link Access to the network can be made from any node
28. Network Gateway If connection to the logger is lost… Data are stored within the network until connection with the logger is restored
29. Network Gateway When connection is restored, the logger can collect data from network
30. New wireless sensor nodes are installed in a nearby location The nodes are out of range of the working network … and a brick wall is in the way Placing two nodes as repeaters, the new sensors are able to connect to the existing network
31. Placing two nodes as repeaters, the new sensors are able to connect to the existing network
