Wireless communication networks with probe response
In one example, a method for providing probe responses in a wireless communication network includes determining, in response to a broadcast probe request from a station, to respond to the broadcast probe request based on whether the station previously acknowledges a previous broadcast probe response from an access point. Additionally, the method includes transmitting a probe response to the station based on the determination.
1. An access point for a wireless network
comprising:
a memory comprising executable instructions; and
a processor that executes the executable instructions to enable a station to discover the access point, the processor to:
receive a probe request from the station;
in response to the probe request, determine whether to respond to the probe request based on whether the access point received a previous acknowledgment from the station in response to a previous probe response from the access point within a specified threshold of time between the previous acknowledgement and the probe request;
transmit a probe response to the station if the access point did not receive the previous acknowledgment from the station within the specified threshold of time; and
do not transmit the probe response to the station if the access point did receive the previous acknowledgment from the station within the specified threshold of time.
2. The apparatus of claim 1 , wherein determining whether to respond comprises determining that an acknowledgement log of the access point does not include an entry for the station.
3. The apparatus of claim 1 , wherein the processor is to:
generate an entry to an acknowledgement log of the access point in response to
the previous acknowledgement from the station responding to
previous probe response from the access point; and
record the entry in the acknowledgment log.
4. The apparatus of claim 3 , wherein the entry includes:
an identifier (ID) of the station; and
a time of the previous acknowledgement.
5. The apparatus of claim 3 , wherein determining whether the access point received a previous acknowledgment from the station in response to the previous probe response from the access point within the specified threshold of time between the previous acknowledgement and the probe request is based on the entry.
6. The apparatus of claim 1 , wherein the processor create a wireless network connection between the station and the access point.
7. One or more tangible, non-transitory computer readable media to enable a station to discover an access point in a wireless communication network, comprising a plurality of instructions that, in response to being executed on a processor, cause the processor to:
receive a probe request from the station;
in response to the probe request from the station, determine whether to respond to the probe request based on whether the access point received a previous acknowledgment from the station in response to a previous probe response from the access point within a specified threshold of time between the previous acknowledgement and the probe request; and
transmit a probe response to the station if the access point did not receive the previous acknowledgment from the station within the specified threshold of time; and
do not transmit the probe response to the station if the access point did receive the previous acknowledgment from the station within the specified threshold of time.
8. The one or more tangible, non-transitory computer readable media of claim 7 , wherein determining to respond comprises determining that an acknowledgement log of the access point does not include an entry for the station.
9. The one or more tangible, non-transitory computer readable media of claim 7 , wherein the processor is to:
generate an entry to an acknowledgment log of the access point in response to the previous acknowledgement from the station responding to the previous probe request; and
record the entry in the acknowledgement log.
10. The one or more tangible, non-transitory computer readable media of claim 9 , wherein the entry includes:
an identifier (ID) of the station; and
a time when the access point determines the station previously acknowledges the previous broadcast probe response from the access point.
11. The one or more tangible, non-transitory computer readable media of claim 10 , wherein determining the access point received a previous acknowledgment from the station in response to the previous probe response from the access point within the specified threshold of time between the previous acknowledgement and the probe request is based on the entry.
12. The one or more tangible, non-transitory computer readable media of claim 7 , wherein the processor is to create a wireless network connection between the station and the access point.
13. A method of operating an access point in a wireless communication network, comprising:
receiving a probe request from a station;
in response to the probe request, determining whether to respond to the probe request based on whether the access point received a previous acknowledgment from the station in response to a previous probe response from the access point within a specified threshold of time between the previous acknowledgement and the probe request; and
transmitting a probe response to the station if the access point did not receive the previous acknowledgment from the station within the specified threshold of time; and
do not transmit the probe response to the station if the access point did receive the previous acknowledgment from the station within the specified threshold of time.
14. The method of claim 13 , wherein determining whether to respond includes determining that an acknowledgement log of the access point does not include an entry for the station.
15. The method of claim 13 comprising:
generating an entry to an acknowledgment log of the access point in response to previous acknowledgement from the station responding to the previous probe request; and
recording the entry in a computer memory of the one access point.
16. The method of claim 15 , wherein the entry includes:
an identifier (ID) of the station; and
a time when the access point determines the station previously acknowledged the previous probe response from the access point.
17. The method of claim 16 , wherein determining whether to respond is based on when the station previously acknowledged the previous probe response.
18. The method of claim 17 , wherein determining whether the access point received a previous acknowledgment from the station in response to the previous probe response from the access point within the specified threshold of time between the previous acknowledgement and the probe request is based on the entry.
19. The method of claim 13 , comprising creating a wireless network connection between the station and the access point.
