determine whether the packet was received again during the time period; and

transmit the packet to relay the packet to the Bluetooth™ mesh network in response to determining that the packet was not received again during the time period.

2. The apparatus of claim 1 , wherein the processing device is further configured to:

refrain from transmitting the packet to the Bluetooth™ mesh network in response to determining that the packet was received again during the time period.

3. The apparatus of claim 1 , wherein the Bluetooth™ mesh network comprises a plurality of Bluetooth™ devices and wherein packets are communicated by relaying the packets via the plurality of Bluetooth™ devices.

4. The apparatus of claim 3 , wherein to transmit the packet, the processing device is further configured to:

broadcast the packet to the plurality of Bluetooth™ devices of the Bluetooth™ mesh network.

5. The apparatus of claim 1 , wherein to determine the measure of strength of the radio-frequency signal, the processing device is further configured to:

determine a received signal strength indication (RSSI) for the radio-frequency signal.

6. The apparatus of claim 1 , wherein a duration of the time period is correlated with the measure of strength of the radio-frequency signal.

7. The apparatus of claim 1 , wherein to determine the time period, the processing device is further configured to:

calculate the time period based on a function of the measure of strength of the radio-frequency signal.

8. The apparatus of claim 1 , wherein to determine the time period, the processing device is further configured to:

select the time period from a plurality of time periods, wherein the plurality of time periods is associated with a plurality of ranges of strengths of the radio-frequency signal.

9. A method, comprising:

receiving a packet transmitted to a Bluetooth™ mesh network via a radio-frequency signal;

determining a measure of strength of the radio-frequency signal;

determining a time period to wait to receive the packet again based on at least the measure of strength of the radio-frequency signal;

determining whether the packet was received again during the time period; and

transmitting the packet to relay the packet to the Bluetooth™ mesh network in response to determining that the packet was not received again during the time period.

10. The method of claim 9 , further comprising:

refraining from transmitting the packet to the Bluetooth™ mesh network in response to determining that the packet was received again during the time period.

11. The method of claim 9 , wherein the Bluetooth™ mesh network comprises a plurality of Bluetooth™ devices and wherein packets are communicated by relaying the packets via the plurality of Bluetooth™ devices.

12. The method of claim 11 , wherein transmitting the packet comprises:

broadcasting the packet to the plurality of Bluetooth™ devices of the Bluetooth™ mesh network.

13. The method of claim 9 , wherein determining the measure of strength of the radio-frequency signal comprises:

determining a received signal strength indication (RSSI) for the radio-frequency signal.

14. The method of claim 9 , wherein a duration of the time period is correlated with the measure of strength of the radio-frequency signal.

15. The method of claim 9 , wherein determining the time period comprises:

calculating the time period based on a function of the measure of strength of the radio-frequency signal.

16. The method of claim 9 , wherein determining the time period comprises:

selecting the time period from a plurality of time periods, wherein the plurality of time periods is associated with a plurality of ranges of strengths.

17. A system comprising:

a first node configured to transmit a packet to a Bluetooth™ mesh network via a radio-frequency signal; and

a second node configured to:

receive the packet;

determine a strength of the radio-frequency signal;

determine a time period to wait to receive the packet again based on the measure of strength of the radio-frequency signal;

determine whether the packet was received again during the time period; and

transmit the packet to relay the packet to the Bluetooth™ mesh network in response to determining that the packet was not received again during the time period.

18. The system of claim 17 , wherein the second node is further configured to:

refrain from transmitting the packet to the Bluetooth™ mesh network in response to determining that the packet was received again during the time period.

19. The system of claim 17 , wherein to determine the time period, the second is configured to:

calculate the time period based on a function of the measure of strength of the radio-frequency signal.
