Dataset of BitTorrent traffic from Korea Telecom's mobile WiMAX network, 
collected in March 2010.

We carry out the experiments by three laptops (Intel Core 2 Duo CPU and 2GB 
RAM), and three USB dongles embedded with mobile WiMAX modem (KWM-U1000 and its
upgraded version KWM-U1800). Another desktop computer (AMD Triple-Core CPU and 
2GB RAM) is used to measure the performance of an Ethernet host in campus 
network.

To measure the behaviors of peers of P2P applications, we modify the 
open-source BitTorrent client, Vuze, to monitor its operations. We select only 
popular video contents (25 min episodes of a popular sitcom), which have at 
least 300 seeds; their file sizes range around 300-400 MB. We capture packet 
headers by WinDump, and analyze the traces by Wireshark and TCPTrace to monitor
the P2P operations and measure the throughput, RTT and so on. The XRO7000 
toolkit is used to observe the WiMAX link layer activities such as the handover
controlling messages. 

We consider three mobility scenarios of WiMAX hosts: 

(1) static: A subscriber station (SS) is located inside university campus 
network, where a single base station (BS) and a few repeaters cover the entire 
campus area. The location of the SS is inside a building, which is about 800 
meters away from the BS. 

(2) subway: We take subway line 4 in Seoul Metro, from Sadang station to 
Myeong-dong Station. Distance between two stations is about 12km and it 
takes about 20 minutes by subway train. There are total 10 subway stations
on the route including the above two stations. Note that there is Han 
river (about 2 km wide) in-between. At every subway station, a single BS 
is deployed, and one or more repeaters are installed in a tunnel between 
adjacent BSs to enhance the radio signal. Therefore, handovers occur 
whenever a subway train moves from one station to another. 

(3) bus: We take bus 501 from Seoul National University to Seoul Railway 
Station. The distance of the bus route is about 11km and it takes about 30
minutes. (We avoid the rush hour.)

For comparison, we also captured traces of downloads on a host connected to 
100Mbps Ethernet on the campus network of Seoul University.

In tcpdump captures, the payload was cut off by resampling with tcpreplay 
and tcpdump, and the header was anonymized by tcprewrite.

This is a traceset of packet captures of BitTorrent traffic from WiMAX network
in Seoul from March 2010.

BitTorrent packets on Seoul WiMAX network were generated by downloading 25 
minute sitcoms in three mobility scenarios and captured by WinDump. BitTorrent
packets were also generated and captured by a host connected to Ethernet on
the campus network of Seoul National University. WiMAX link layer packets were 
captured by XRO7000 toolkit.

The payload was cut off by resampling with tcpreplay and tcpdump, and the
header was anonymized by tcprewrite.

[Paper] kim-measurement

top

As mobile Internet environments are becoming dominant, how to revamp P2P 
operations for mobile hosts is gaining more and more attention. In this paper, 
we carry out empirical traffic measurement of BitTorrent service in various 
settings (static, bus and subway) in commercial WiMAX networks. To this end, we 
analyze the connectivity among peers, the download throughput/stability, and 
the signaling overhead of mobile WiMAX hosts in comparison to a wired 
(Ethernet) host. We find out the drawbacks of BitTorrent operations in mobile 
Internet are characterized by lower connection ratio, unstable connections 
amongst peers, and higher control message overhead.
