Abstract 

Dataset of network performance data collected with WiScape framework from three commercial cellular wireless networks.

last modified : 2012-08-03

release date : 2012-08-03

date/time of measurement start : 2008-03-13

date/time of measurement end : 2011-05-05

collection environment : We carried out extensive measurements on wide area wireless networks over a duration of more than 1 year, spanning a geographical area of more than 155 sq. km. in and around Madison, WI, a road stretch of 240 km between Madison, WI, and Chicago, IL, and locations in New Brunswick, NJ, and Princeton, NJ. We collected measurement samples on three 3G cellular networks.

network configuration : Our measurement setup consists of a measurement coordinator running on a desktop in our university laboratory, with well-provisioned connectivity to the Internet. This coordinator periodically requests and collects measurements from different client devices (based on Windows and Linux platforms). All of our measurements were collected using laptops or single-board computers equipped with different models of cellular modems (some were USB-based, and others were PCMCIA).

data collection methodology : We collected data from three different cellular networks with nation-wide footprints, referred to as NetA, NetB, and NetC. The data collection process has been ongoing in multiple stages for more than one year now, and different clients in our measurement setup had different capabilities and characteristics.

sanitization : We removed unnecessary information which we collected but didn't use for our paper.

Network performance data collected with WiScape framework in 2009-2011.

  • files: standalone.tgz, README_standalone.txt, wireover.tgz, README_wirover.txt, roadSeg.tgz, README_roadSeg.txt, prox.tgz, README_prox.txt, spot.tgz, README_spot.txt
  • description: Traceset of network performance data collected with WiScape framework from three commercial cellular wireless networks.
  • measurement purpose: Network Performance Analysis
  • methodology: Our measurement setup consists of a measurement coordinator running on a desktop in our university laboratory, with well-provisioned connectivity to the Internet. This coordinator periodically requests and collects measurements from different client devices (based on Windows and Linux platforms). Different clients in our measurement setup had different capabilities and characteristics.

wisc/wiscape/groundtruth Traces

  • standalone: TCP throughput measurements collected on public transit buses in Madison.
    • configuration: Linux-based measurement nodes equipped with a single cellular network interface (NetB) were mounted on public transit buses in Madison, WI. We collected TCP throughput measurements over NetB by sending a 1MB file to the client.
    • format:

      We have clustered the data points into regions of 250 meter radius. We have a

      file for each of the clusters and 1184 clusters in all.

      The longitude and latitute of the center of the cluster is embedded in the file

      name. Each row of the file has data in the following format:

      UNIX timestamp,network name,throughput in Kbps.

  • wirover: Ping-based RTT measurements collected on public transit buses in Madison.
    • configuration: The collection process is the newer incarnation of the standalone collection process, in which all of the bus-mounted nodes are now equipped with two network interfaces (for NetB and NetC) and provide free WiFi service to bus passengers using the multi-network setup. Over time, these buses generated multiple measurement values for each location along this path stretch.
    • format:

      The files with prefix MM correspond to buses belonging to Madison Metro

      transit system. The files with VG prefix correspond to a Van-Galder bus running

      between Chicago and Madison.

      Each row of the files has data in the following format:

      UNIX timestamp,Latitude,Longitude,Bus speed(from GPS in Km/hr),Bus id,network

      name,RTT (in msec).

  • roadseg: TCP and UDP packet traces collected while driving across a stretch of roadway on personal automobiles.
    • configuration: The data was collected over NetB and NetC.
    • format:

      Each row of the file has data (measured packet information) in the following

      format:

      network name,protocol,pkt_size,pkt sequence number,measurement duration,date,

      time,latitude,longitude

  • proximate: TCP and UDP packet traces collected by driving around in a car.
    • configuration: The traces were collected over NetA, NetB, and NetC.
    • format:

      Each row of the file has data (measured packet information) in the following

      format:

      network name,protocol,pkt_size,pkt sequence number,measurement duration,date,

      time,latitude,longitude

  • spot: TCP and UDP packet traces collected indoors at one specific location.
    • configuration: The traces were collected over NetA, NetB, and NetC.
    • format:

      Each row of the file has data (measured packet information) in the following

      format:

      network name,protocol,pkt_size,pkt sequence number,measurement duration,date,

      time,latitude,longitude

These datasets are part of Community Resource for Archiving Wireless Data (CRAWDAD). CRAWDAD began in 2004 at Dartmouth College as a place to share wireless network data with the research community. Its purpose was to enable access to data from real networks and real mobile users at a time when collecting such data was challenging and expensive. The archive has continued to grow since its inception, and starting in summer 2022 is being housed on IEEE DataPort.
