Abstract

Techniques are disclosed herein for providing wireless network communication nodes with opt-out capabilities. Such capabilities may, for example, allow particular customers to opt out of a typical full-scale communication mode such that their associated equipment operates at least temporarily in a limited communication mode. The limited communication mode may limit customer exposure to emissions resulting from RF communications near their homes or other areas, which may be attractive to customers such as those with health or other emission-related concerns.

Claims

1. A wireless network comprising:

a central node; and

a plurality of communication nodes in wireless communication with the central node, each of the communication nodes having a wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate communication nodes serving as relays,

wherein one or more of the communication nodes operate in a limited communication mode in which they are scheduled to transmit data less frequently than one or more other communication nodes not operating in the limited communication mode, wherein the communication nodes operating in the limited communication mode are prohibited from serving as relays, and wherein the communication nodes operating in the limited communication mode are configured to respond to fewer types of requests and/or to transmit fewer types of messages than the one or more other communication nodes not operating in the limited communication mode.

2. The wireless network of claim 1, wherein at least one of the communication nodes is reconfigurable to be switched into and out of operation in the limited communication mode.

3. The wireless network of claim 1, wherein the central node maintains a first schedule and a second schedule, wherein the first schedule indicates a first frequency of times at which to read data from the one or more other communication nodes not operating in the limited communication mode, wherein the second schedule indicates a second frequency of times at which to read data from the one or more communication nodes operating in the limited communication mode, wherein the first frequency is more frequent than the second frequency.

4. The wireless network of claim 1, wherein at least one of the communication nodes operating in the limited communication mode has an associated schedule that indicates times at which to power up the communication node'"'"'s transceiver.

5. The wireless network of claim 1, wherein, for each communication node operating in the limited communication mode, the central node determines the wireless communication path for the central node and also attempts to determine one or more additional communication paths from the communication node to the central node.

6. The wireless network of claim 1, wherein at least one of the communication nodes operating in the limited communication mode is configured to allow its transceiver to remain powered on throughout a duration of its operation in the limited communication mode.

7. The wireless network of claim 1, wherein the communication nodes operating in the limited communication mode are permitted to transmit power outage and power restoration messages.

8. The wireless network of claim 1, wherein the communication nodes operating in the limited communication mode are permitted to respond only to read requests.

9. The wireless network of claim 1, wherein:

for each of the one or more other communication nodes not operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a first threshold time period, the central node causes a new wireless communication path to be determined for the communication node, and

wherein, for each communication node operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a second threshold time period, the central node causes a new wireless communication path to be determined for the communication node, and

wherein the first threshold time period is shorter than the second threshold time period.

19. The method of claim 8, wherein the first communication node is permitted to respond only to read requests while operating in the limited communication mode.

10. In a wireless network comprising a central node and a plurality of communication nodes in wireless communication with the central node, each of the communication nodes having a wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate communication nodes serving as relays, wherein one or more of the communication nodes operate in a limited communication mode in which they are scheduled to transmit data less frequently than one or more other communication nodes not operating in the limited communication mode, the method comprising:

receiving an indication that a first communication node is designated for operation in the limited communication mode;

scheduling reading of data from the first communication node to be performed less frequently than reading of data from the one or more other communication nodes; and

causing the first communication node to be configured to respond to fewer types of requests and/or to transmit fewer types of messages than the one or more other communication nodes not operating in the limited communication mode.

11. The method of claim 10, further comprising designating the first communication node as being prohibited from serving as a relay while operating in the limited communication mode.

12. The method of claim 10, further comprising receiving an indication that the first communication node is no longer designated for operation in the limited communication mode.

13. The method of claim 10, wherein the central node maintains a first schedule and a second schedule, wherein the first schedule indicates a first frequency of times at which to read data from the one or more other communication nodes not operating in the limited communication mode, wherein the second schedule indicates a second frequency of times at which to read data from the one or more communication nodes operating in the limited communication mode, wherein the first frequency is more frequent than the second frequency, and wherein the first communication node is associated with the second schedule.

14. The method of claim 10, further comprising associating the first communication node with a schedule that indicates times at which to power up the first communication node'"'"'s transceiver.

15. The method of claim 10, wherein the first communication node is configured to allow its transceiver to remain powered on while operating in the limited communication mode.

16. The method of claim 10, further comprising attempting to determine one or more additional communication paths from the first communication node to the central node.

17. The method of claim 10, wherein:

for each of the one or more other communication nodes not operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a first threshold time period, the central node causes a new wireless communication path to be determined for the communication node, and

wherein, for the first communication mode, when the central node does not receive an indication that the first communication node has performed a network transmission within a second threshold time period, the central node causes a new wireless communication path to be determined for the first communication node, and

wherein the first threshold time period is shorter than the second threshold time period.

18. The method of claim 10, wherein the first communication node is permitted to transmit power outage and power restoration messages while operating in the limited communication mode.

20. A wireless network comprising:

a central node; and

a plurality of communication nodes in wireless communication with the central node, each of the communication nodes having a wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate communication nodes serving as relays,

wherein one or more of the communication nodes operate in a limited communication mode in which they are scheduled to transmit data less frequently than one or more other communication nodes not operating in the limited communication mode,

wherein, for each of the one or more other communication nodes not operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a first threshold time period, the central node causes a new wireless communication path to be determined for the communication node, and

wherein, for each communication node operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a second threshold time period, the central node causes a new wireless communication path to be determined for the communication node, and

wherein the first threshold time period is shorter than the second threshold time period.
