LOCOSMOTION

Name of the competing system:  LOCOSMOTION

Name and email of the responsible person:  Ngewi Fet < ngewi.fet(at)uni-due.de>

Date and place: 20.06.2012, Duisburg, Germany

Name

[RAW] WiFi Scan Results – list of WiFi access points and their RSSI

Description of the information measured

The Received Signal Strength Indicator (RSSI) of each access point visible at multiple locations in the Living lab

Units

dBm

Example values

-30 dBm, -90 dBm

Frequency of generated data in operation

On the hardware we use, approximately every 1.4 seconds

Name

Acceleration Signal Vector Magnitude [PREPROCESSED]

Description of the information measured

sensor acceleration by the accelerometer and the signal magnitude of the acceleration components;

Units

m/s²

Example values

9.8 m/s² and 10 m/s²

Frequency of generated data in operation

Acceleration is generated at frequency of approximately 50Hz and the vector magnitude is computed at a similar rate.

 

After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).

  1. A static WLAN fingerprint map as array of arrays that include: [x,y, DeviceRadio ID, {SignalType, AccessPoint MAC, RSSI, Channel frequency, SSID} * n  ]
  2. Acceleration Magnitude values during the localization phase as a simple array of values
    • Where n is the number of access points visible at each point

Files:

-          A file containing the fingerprint map (txt file of comma-separated values)

-          A file containing the acceleration values (txt files)
