Overview

This package provides tools for logging statistics from a router using ddwrt OpenSource firmware and publishing them over ROS.

Nodes

ddwrt

The ddwrt ROS Node publishes information about the Access Point that the router is currently connected to as well as survey information about all the Access Points that the router can see.

Published Topics

ddwrt/sitesurvey (wifi_ddwrt/SiteSurvey)
  • A survey of all the Access Points that the router sees with their associated signal strength and noise values.
ddwrt/accesspoint (wifi_ddwrt/AccessPoint)
  • Information about the Access Point that the router is currently connected to including signal strength and noise values.

Parameters

~router (string, default: "10.68.0.5")
  • The ip address of the router we wish to publish information about.
~username (string, default: root)
  • Username to connect to router
~password (string, default: )
  • Password to connect to router.

monitor

The monitor node publishes a visualization marker to rviz that displays between 1-5 bars over the robot's head according to the signal strength of the Access Point the robot is currently connected to.

Subscribed Topics

ddwrt/sitesurvey (wifi_ddwrt/SiteSurvey)
  • A survey of all the Access Points that the router sees with their associated signal strength and noise values.
ddwrt/accesspoint (wifi_ddwrt/AccessPoint)
  • Information about the Access Point that the router is currently connected to including signal strength and noise values.

Published Topics

visualization_marker (visualization_msgs/Marker)
  • A marker to display bars above the robot's head in rviz

analysis

The analysis node logs information about signal strength from the Access Points that the robot connects to and displays visualizations of this information on a map which it saves as a png image.

Subscribed Topics

ddwrt/sitesurvey (wifi_ddwrt/SiteSurvey)
  • A survey of all the Access Points that the router sees with their associated signal strength and noise values.
ddwrt/accesspoint (wifi_ddwrt/AccessPoint)
  • Information about the Access Point that the router is currently connected to including signal strength and noise values.

Published Topics

visualization_marker (visualization_msgs/Marker)
  • Markers corresponding to the signal strength of a given Access Point at each position a reading was taken.

output

The analysis node will save a file called "static_map.png" on exit that displays signal strength information for a run.
