Abstract

The disclosed computer-implemented method may include receiving, by a receiver node of a wireless network, a packet sent by a transmitter node of the wireless network and identifying a packet type of the received packet. The method may also include determining, based on at least the identified packet type, a signal strength threshold and comparing a signal strength of the received packet with the signal strength threshold. The method may further include processing, by the receiver node, the received packet when the signal strength satisfies the signal strength threshold. Various other methods, systems, and computer-readable media are also disclosed.

First claim

What is claimed is:

1 . A computer-implemented method comprising:
receiving, by a receiver node of a wireless network, a packet sent by a transmitter node of the wireless network, resulting in a received packet; identifying a packet type of the received packet; determining, based on at least the identified packet type, a signal strength threshold; comparing a signal strength of the received packet with the signal strength threshold; and processing, by the receiver node, the received packet when the signal strength satisfies the signal strength threshold.

2 . The method of claim 1 , wherein the signal strength threshold comprises a filter value range including an upper threshold and a lower threshold.

3 . The method of claim 1 , wherein the signal strength threshold is determined based on a distance between the receiver node and the transmitter node.

4 . The method of claim 3 , wherein the distance is determined by mapping a topology of the wireless network using statistical analysis.

5 . The method of claim 1 , wherein the signal strength threshold is based on an interference management scan of the wireless network that measures an interference between each link for every pair of transmitter and receiver nodes in the wireless network.

6 . The method of claim 5 , further comprising adjusting the signal strength threshold for each link based on the interference management scan.

7 . The method of claim 6 , further comprising increasing the signal strength threshold for a link when an interference measurement for the link is greater than an interference threshold.

8 . The method of claim 6 , further comprising decreasing the signal strength threshold for a link when an interference measurement for the link is less than an interference threshold.

9 . The method of claim 1 , further comprising adjusting the signal strength threshold based on a live link performance for a link between the transmitter node and the receiver node.

10 . The method of claim 9 , further comprising decreasing the signal strength threshold when a false negative count of the link is greater than a false negative threshold.

11 . The method of claim 9 , further comprising increasing the signal strength threshold when a false positive count of the link is greater than a false positive threshold.

12 . The method of claim 1 , wherein processing the received packet includes placing the received packet in a queue for processing packets.

13 . The method of claim 1 , wherein processing the received packet includes reading a destination of the packet.

14 . The method of claim 1 , further comprising dropping the received packet when the signal strength does not satisfy the signal strength threshold.

15 . The method of claim 1 , wherein the packet type includes a control packet or a data packet.

16 . A system comprising:
an antenna for communicating with a wireless network; at least one physical processor; and a physical memory comprising computer-executable instructions that, when executed by the physical processor, cause the physical processor to:
receive, via the antenna, a packet sent by a transmitter node of the wireless network, resulting in a received packet;
identify a packet type of the received packet;
determine, based on at least the identified packet type, a signal strength threshold;
compare a signal strength of the received packet with the signal strength threshold; and
process the received packet when the signal strength satisfies the signal strength threshold.

17 . The system of claim 16 , wherein the signal strength threshold is determined based on a distance between the transmitter node, and the distance is determined by mapping a topology of the wireless network using statistical analysis.

18 . The system of claim 16 , further comprising adjusting the signal strength threshold for each link based on an interference management scan of the wireless network that measures an interference between each link for every pair of transmitter and receiver nodes in the wireless network by:
increasing the signal strength threshold for a link when an interference measurement for the link is greater than an interference threshold; and decreasing the signal strength threshold for a link when an interference measurement for the link is less than the interference threshold.

19 . The system of claim 16 , further comprising adjusting the signal strength threshold based on a live link performance for a link with the transmitter node by:
decreasing the signal strength threshold when a false negative count of the link is greater than a false negative threshold; and increasing the signal strength threshold when a false positive count of the link is greater than a false positive threshold.

20 . A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
receive, via an antenna, a packet sent by a transmitter node of a wireless network, resulting in a received packet; identify a packet type of the received packet; determine, based on at least the identified packet type, a signal strength threshold; compare a signal strength of the received packet with the signal strength threshold; and process the received packet when the signal strength satisfies the signal strength threshold.
