Abstract
Various embodiments disclose a computer-implemented method for sending a message associated with an outage event, comprising, at a first node in a network, receiving a key from a second node in the network, wherein the second node is adjacent to the first node; storing the key in a first memory, wherein the first memory is capable of operating in a low power mode; detecting an outage event; in response to detecting the outage event, operating a first processor in the low power mode; and via the first processor operating in the low power mode: generating a message, securing the message using the key, and sending the message to the second node.
Claims20
A computer-implemented method for sending a message associated with an outage event, comprising, at a first node in a network:
- receiving a key from a second node in the network, wherein the second node is adjacent to the first node;
- storing the key in a first memory, wherein the first memory is capable of operating in a low power mode;
- detecting an outage event;
- in response to detecting the outage event, operating a first processor in the low power mode;
- and
- via the first processor operating in the low power mode:
- generating a message;
- securing the message using the key;
- and
- sending the message to the second node.
One or more non-transitory computer-readable media at a first node in a network, the one or more computer-readable storage media storing program instructions that, when executed by one or more processors at the first node, cause the one or more processors at the first node to perform the steps of:
- receiving a key from a second node in the network, wherein the second node is adjacent to the first node;
- storing the key in a first memory, wherein the first memory is capable of operating in a low power mode;
- detecting an outage event;
- in response to detecting the outage event, operating a first processor included in the one or more processors in the low power mode;
- and
- via the first processor operating in the low power mode:
- generating a message;
- securing the message using the key;
- and
- sending the message to the second node.
A system in a wireless mesh network, comprising:
- a plurality of nodes included in a wireless mesh network;
- a first node included in the plurality of nodes;
- a second node included in the plurality of nodes and adjacent to the first node, the second node configured to perform the steps of:
- receiving a key from the first node;
- storing the key in a first memory at the second node, wherein the first memory is capable of operating in a low power mode;
- detecting an outage event at the second node;
- in response to detecting the outage event, operating a first processor at the second node in the low power mode;
- and
- via the first processor operating in the low power mode:
- generating a message;
- retrieving the key from the first memory, wherein the first memory is operating in the low power mode;
- securing the message using the key;
- and
- sending the message to the first node.
