Understanding Channel and Interface Heterogeneity in Multi-Radio Multi-Channel Wireless Networks

The dataset consist of measurements from two different wireless mesh network testbeds (802.11g and 802.11a). The 802.11g testbed uses 10 Dell latitude D510 laptops each with one Atheros chipset based D-link DWL AG660 PCMCIA 802.11a/b/g card with an internal antenna. The transmit powers are fixed to 15 dBm and data rate to 11 Mbps. Measurements from this testbed were collected on 54 different links on three orthogonal channels 1, 6, 11 (2412, 2437 and 2462 MHz respectively) in the 802.11g band. The 802.11a testbed consists of 13 nodes each of which is a Soekris net4801 single board computer (SBC). The PCI-slot in the SBC is expanded into 4 miniPCI slots using a PCI-to-miniPCI adapter. Four 802.11a/b/g miniPCI wireless cards based on Atheros chipset with external antennas are used in each mesh node. The transmit powers are fixed to 15 dBm and data rate to 6 Mbps. Measurements from this testbed were collected on 78 different links in 13 orthogonal channels (between 5180-5825 Mhz) in the 802.11a band.

There are three different directories consisting three different sets of measurements.

(i) 802_11a

This directory consist of measurements on 78 links each on 13 orthogonal channels in 802.11a band . In total, there are 1014 files.

(ii) 802.11g

This directory consist of measurements on 54 links each on 3 orthogonal channels in 802.11g band. In total, there are 162 files.

(iii) interface

This directory consist of measurements on 20 links working on channel 64 in the 802.11 band. For each link, measurements were done in 16 possible interface pairs. Note that our multi-radio node has 4 radios. So for any link there are 16 possible interface pairs. In total, there are 320 files.

DATAFORMAT of all files:

All the data files are in csv format. The records in each file are of the following format

<MAC_TIME_STAMP>,<PACKET_TYPE>,<CHANNEL>,<SNR>,<RSS>,<NOISE>,<DATA_RATE>,<MAC_SEQUENCE_NUMBERS>

More details are in the following paper.
