Abstract

A method and system for replacing a first wireless node in an IoT system includes determining, by the first wireless node, that the first wireless node needs imminent replacement. The determination may be made, for example, based on a battery of the first wireless node being below a threshold level. The first wireless node initiates a discovery protocol for a second wireless node installed in proximity to the first wireless node, the second wireless node installed to replace the first wireless node. Upon discovery of the second wireless node, the first wireless node transmits a configuration file to the second wireless node, which the second wireless node copies to a storage of the second wireless node. The second wireless node configures itself to operate as a replacement for the first wireless node in the IoT system, based at least in part on the copied configuration file.

Claims (17)

1. A method comprising:

receiving, by an intermediary device, an indication that a first wireless node of an internet of things (IoT) system is in need of replacement using wireless communication;

receiving, by the intermediary device, a notification from the second wireless node that it is ready to receive a configuration file, wherein the second wireless node is intended to replace the first wireless node;

syncing, by the intermediary device, the first wireless node with the second wireless node for wireless communication; and

instructing, by the intermediary device, both the first wireless node and the second wireless node to discover each other within a specified time range, wherein

the first wireless node and the second wireless node discover each other during the specified time range, and complete a transfer of a configuration file from the first wireless node to the second wireless node.

2. The method of claim 1 , wherein the intermediary device is a gateway device located within a wireless communication range of the first wireless node.

3. The method of claim 1 , wherein the intermediary device is a line-powered device.

4. The method of claim 1 , wherein the first wireless node and the second wireless node are both battery powered.

5. The method of claim 1 , wherein each of the first wireless node and the second wireless node is a tape node.

6. The method of claim 1 , wherein the intermediary device is solar powered.

7. The method of claim 1 , wherein the indication is received from a server of the IoT system.

8. The method of claim 7 , further comprising:

prior to syncing, searching, by the intermediary device for a wireless device broadcasting an identifier that corresponds to the first wireless node, wherein the indication comprises the identifier.

9. The method of claim 7 , further comprising:

prior to syncing, after receiving the indication, searching, by the intermediary device for a wireless device broadcasting an identifier that corresponds to the second wireless node, wherein the indication comprises the identifier.

10. The method of claim 1 , wherein the intermediary device is a client device associated with a user.
