The code is here.

It presents a menu to the user, who can get different statistics from the APs and the connected STAs.

See the application running in the following video: DemoStatistics Video

It distinguishes between

  • Internal statistics
  • External statistics
  • Active scanning (Matrix of "distance in dBs")
  • Passive scanning (Matrix of RSSI heard from STAs)

This is an example of the internal statistics obtained in the internal wireless interface of an AP (Agent):

[DemoStatistics] =======Internal statistics=======
[DemoStatistics] Agent [0]: /192.168.1.13
[DemoStatistics] 	Txpower: 10 dBm
[DemoStatistics] 	Channel: 1
[DemoStatistics] 	Last heard: 389 ms ago
[DemoStatistics]
[DemoStatistics] Agent [1]: /192.168.1.15
[DemoStatistics] 	Txpower: 10 dBm
[DemoStatistics] 	Channel: 6
[DemoStatistics] 	Last heard: 1893 ms ago
[DemoStatistics]
[DemoStatistics] Agent [2]: /192.168.1.14
[DemoStatistics] 	Txpower: 10 dBm
[DemoStatistics] 	Channel: 6
[DemoStatistics] 	Last heard: 142 ms ago

This is an example of the statistics of a single STA:

		init time: 1519733525.415637841 sec
		end time: 1519733574.344232353 sec

Passive scanning can also be used to gather information about the wireless environment:

[DemoStatistics]
	Select agent [0-2]: 0
	Select channel to scan [1-11]: 2
	Select time to scan (msec): 2000
[DemoStatistics] <<<<< Scanning in channel 2 >>>>>>
	Station MAC: 76:A0:26:C1:E1:AA
		num packets: 1

		air time: 1.008 ms
		init time: 1519733747.339689262 sec
		end time: 1519733747.339826638 sec
		AP of client: unknown
		Channel of AP: unknown
		Code: non-Wi-5 STA

		Code: non-Wi-5 STA

This is an example of the active scanning statistics with 4 APs:

Passive scanning can also be used to gather information about the STAs associated to Wi5 APs:

[DemoStatistics] ==============Passive scanning (Matrix of RSSI)==============
[DemoStatistics] AP /192.168.1.7 in channel: 3
[DemoStatistics] AP /192.168.1.1 in channel: 1

[DemoStatistics] AP /192.168.1.2 in channel: 6
