Click-based odin agent that runs on access points

Odin agent

We are adding interesting info in this wiki: https://github.com/Wi5/odin-wi5/wiki

Odin agents run on physical APs, and are implemented as Click elements. Agents contain the logic for the Wi-Fi split-MAC and LVAP handling. Agents also record information about clients using radiotap headers, and communicate with the Odin Master over the Odin control channel. The physical AP hosting the agent also requires a slightly modified Wi-Fi device driver to generate ACK frames for every LVAP that is hosted on the AP.

Source files for Odin agent:

src/odinagent{.cc,.hh}

These are the Click OdinAgent element files. They've only been tested in userspace mode so far. To build:

1. Add these files to /elements/local/

2. Build Click with the --enable-local and --enable-userlevel flag.

3. $ make

agent-click-file-gen.py

Click file generator for the agent. Configure and use this script to generate the appropriate Odin agent click file.

This is an example of how to use the python command:

$ python agent-click-file-gen.py 4 50  14:CC:20:AC:72:91 192.168.1.129 2819 /sys/kernel/debug/ieee80211/phy0/ath9k/bssid_extra odin-unizar 192.168.1.7 0 11 12 25 0

where the parameters have the next meaning:

4 number of the channel

50 size of the queue

14:CC:20:AC:72:91 MAC address of the AP

192.168.1.129 IP address of the Controller

2819 port used to connect with the Controller

/sys/kernel/debug/ieee80211/phy0/ath9k/bssid_extra directory of the debug file

odin-unizar SSID

192.168.1.7 IP address of the AP

0 No click debug info

11 Debug level 1, with Demo appearance (1)

12 6 Mbps of TX rate

25 the Tx power of the AP is 25 dBm (obtained with $iw dev mon0 info)

`0 no hidden mode: the AP will respond to all active scanning requests, even if they have no SSID name
