Sharing duty cycle between devices

1. An apparatus, comprising an internet-of-things (IoT) device, comprising:

a cloud radio transceiver to send data to a cloud connection over a first frequency;

a mesh transceiver to communicate with a mesh network over a second frequency;

a duty cycle calculator to determine if a duty cycle for transmissions from the cloud radio transceiver is nearing a limit, wherein the duty cycle calculator is to activate the mesh transceiver if the duty cycle remaining is greater than a preset limit and a state of charge of a battery to power the IoT device is greater than a threshold; and

a data offloader to send data from the IoT device to a sending device in the mesh network capable of receiving the data and sending the data on to the cloud connection.

2. The apparatus of claim 1 , wherein the IoT device comprises a local transceiver to communicate with the mesh network, and wherein the mesh transceiver and the local transceiver cover different ranges from the IoT device.

3. The apparatus of claim 2 , wherein the mesh transceiver comprises a IEEE 802.15.4 transceiver.

4. The apparatus of claim 2 , wherein the local transceiver comprises a Bluetooth low energy (BTLE) transceiver.

5. The apparatus of claim 1 , wherein the cloud radio transceiver comprises a low power wide area (LPWA) transceiver.

6. The apparatus of claim 1 , comprising a route calculator to calculate a shortest route from the IoT device to the sending device over the mesh network.

7. The apparatus of claim 1 , comprising the battery to power the IoT device.

8. The apparatus of claim 7 , comprising a battery monitor to determine the state of charge on the battery.

9. The apparatus of claim 1 , comprising a network interface controller (NIC) to provide a wired network connection.

10. The apparatus of claim 1 , comprising an interface to couple the IoT device to a sensor, and actuator, or both.

11. The apparatus of claim 1 , the duty cycle calculator to determine if any device in the mesh network is reporting a duty cycle shortage, and, if not, to power down the mesh transceiver.

12. A method for offloading data from an internet of things (IoT) device, comprising:

sending a packet to a cloud device;

computing a duty cycle usage remaining for transmission of data to the cloud device;

activating a mesh transceiver if the remaining duty cycle is greater than a preset upper limit and a state of charge of a battery to power the IoT device is greater than a threshold; and

if the remaining duty cycle is below a preset lower limit, offloading data to a sending device.

13. The method of claim 12 , comprising:

computing the duty cycle usage remaining for transmission of data to the cloud device; and, if the remaining duty cycle is above the preset upper limit,

accepting offloaded data.

14. The method of claim 13 , comprising:

determining a charge on the battery; and, if the charge on the battery is below a threshold,

preventing the mesh transceiver from powering up.

15. The method of claim 12 , comprising:

initializing a mesh transceiver; and

determining if any device in a mesh network is reporting a duty cycle shortage; and, if not,

powering down the mesh transceiver.

16. The method of claim 12 , comprising:

weighting each device in a mesh network by remaining duty cycle;

determining a route to the sending device in the mesh network; and

sending data to the sending device over the mesh network.

17. The method of claim 16 , comprising sending the data to a device in a first range using a low-power transmitter.

18. The method of claim 16 , comprising sending the data to a device in a second range using an intermediate power transmitter.

19. The method of claim 16 , comprising determining the route to the sending device based, at least in part, on a power usage for the route.

20. The method of claim 16 , comprising powering down a mesh transceiver to lower power consumption.

21. The method of claim 16 , comprising formatting a packet to indicate an originating device for offloaded data.

22. A non-transitory machine readable medium, comprising instructions, which when executed, direct a processor in an internet of things (IoT) device to:

communicate over a low power wide area (LPWA) network;

determine a remaining duty cycle for LPWA communications;

determine the remaining duty cycle for units in a mesh network;

send packets over the mesh network to a second device having an excess of duty cycle;

determine if the IoT device has an excess of duty cycle; and

if the IoT device has an excess of duty cycle and a charge of a battery is sufficient to allow offloading of data, allow offloading of data to the IoT device.

23. The non-transitory, machine readable medium of claim 22 , comprising instructions, which when executed, direct the processor to determine a route over the mesh network from the IoT device to the second device.

24. The non-transitory, machine readable medium of claim 23 , comprising instructions, which when executed, direct the processor to send data to the second device over the route.

25. The non-transitory machine readable medium of claim 22 , comprising instructions, which when executed, direct the processor to determine if any device in the mesh network is reporting a duty cycle shortage, and, if not, to power down the mesh transceiver.
