This changes the metrics variables that invove scores to arrays. At the momemnt, there are two bands implemented, 802_11a and 802_11g. Internally, they are chosen based on the frequency of the channel being used. Anything < 2500 MHz is 802_11g, and everything else is 802_11a. Dawn will issue a warning if it finds a frequency greater or equal to 5925 MHz. The upper limit of the 802.11a band, and the start of the next band vary by country, so this will have to be reviewed. The UCI configuration changes. Instead of a single metric config, there will be a global metric config, and one for each band. The non-band-specific configuration will only work in the global config. Any per-band configuration present at the global config will be applied to all bands. Any configuration present at the specific band will override any global values. The following configuration options are split into bands: - ap_weight - ht_support - vht_support - no_ht_support - no_vht_support - rssi - rssi_val - low_rssi - low_rssi_val - freq - chan_util - max_chan_util - chan_util_val - max_chan_util_val Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com> |

DAWN
Decentralized WiFi Controller
Installation
You need full wpad installation and not wpad-basic.
See installation.
LuCI App
There is an luci app called luci-app-dawn.
Setting up Routers
You can find a good guide to configure your router is here. I setup the OpenWRT Router as dumb APs.
Configuration
| Option | Standard | Meaning |
|---|---|---|
| ht_support | '10' | If AP and station support high throughput. |
| vht_support | '100' | If AP and station support very high throughput. |
| no_ht_support | '0' | If AP and station not supporting high throughput. |
| no_vht_support | '0' | If AP and station not supporting very high throughput. |
| rssi | '10' | If RSSI is greater equal rssi_val. |
| low_rssi | '-500' | If RSSI is less than low_rssi_val. |
| freq | '100' | If connection is 5Ghz. |
| chan_util | '0' | If channel utilization is lower chan_util_val. |
| max_chan_util | '-500' | If channel utilization is greater max_chan_util_val. |
| rssi_val | '-60' | Threshold for an good RSSI. |
| low_rssi_val | '-80' | Threshold for an bad RSSI. |
| chan_util_val | '140' | Threshold for an good channel utilization. |
| max_chan_util_val | '170' | Threshold for a bad channel utilization. |
| min_probe_count | '2' | Minimum number of probe requests aftrer calculating if AP is best and sending a probe response. |
| bandwidth_threshold | '6' | Threshold for the receiving bit rate indicating if a client is in an active transmission. |
| use_station_count | '1' | Use station count as metric. |
| max_station_diff | '1' | Maximal station difference that is allowed. |
| eval_probe_req | '1' | Evaluate the incoming probe requests. |
| eval_auth_req | '1' | Evaluate the incomning authentication reqeuests. |
| eval_assoc_req | '1' | Evaluate the incoming association requests. |
| deny_auth_reason | '1' | Status code for denying authentications. |
| deny_assoc_reason | '17' | Status code for denying associations. |
| use_driver_recog | '1' | Allow drivers to connect after a certain time. |
