Collecting power outage notifications in a frequency hopping communication network
First Claim
1. A method, comprising:
- operating in a normal mode in a frequency hopping communication network according to a common broadcast schedule for the network that simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network;
determining a power outage condition;
operating in a power outage mode in response to the power outage condition, wherein the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion; and
wherein the second configured portion is configured based on a tradeoff between relatively higher power outage notification (PON) reliability at correspondingly higher lengths of the second configured portion versus relatively lower PON latency at correspondingly lower lengths of the second configured portion.

Abstract
In one embodiment, a device in a frequency hopping communication network operate in a first mode according to a common broadcast schedule for the network that simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network. In response to determining a power outage condition, the device switches to operation in a power outage mode where the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion. In one embodiment, the device broadcasts one or more power outage notifications (PONs) in response to determining the power outage condition as a reduction of a main power supply at the device. In another embodiment, the device receives a PON while powered as the power outage condition.

15. An apparatus, comprising:
-
a processor; a transceiver configured to communicate with a frequency hopping communication network that operates according to a common broadcast schedule for the network that simultaneously overlays a configured portion of all independently determined unicast listening schedules in the network; and a memory configured to store a process executable by the processor, the process when executed by the processor operable to; operate in a normal mode wherein the common broadcast schedule for the network simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network; determine a power outage condition; operate in a power outage mode in response to the power outage condition, wherein the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion; and wherein the second configured portion is configured based on a tradeoff between relatively higher power outage notification (PON) reliability at correspondingly higher lengths of the second configured portion versus relatively lower PON latency at correspondingly lower lengths of the second configured portion. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A tangible, non-transitory, computer-readable media having software encoded thereon, the software, when executed by a processor on a device in a frequency hopping communication network that operates according to a common broadcast schedule for the network that simultaneously overlays a configured portion of all independently determined unicast listening schedules in the network, operable to:
-
operate in a normal mode wherein the common broadcast schedule for the network simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network; determine a power outage condition; operate in a power outage mode in response to the power outage condition, wherein the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion; and wherein the second configured portion is configured based on a tradeoff between relatively higher power outage notification (PON) reliability at correspondingly higher lengths of the second configured portion versus relatively lower PON latency at correspondingly lower lengths of the second configured portion. - View Dependent Claims (23, 24)
