CRAWDAD uportorwthaachen/vanetjamming2012

This dataset contains traces of 802.11p packets, collected in an anechoic chamber and outdoors in Porto (Portugal) in 2011, with and without the presence of an RF jamming signal with constant, reactive, and pilot jamming patterns. (dataset v. 2014-05-12)

This dataset contains several tracesets of 802.11p communications with and without the presence of a RF jamming signal. The RF jammer has different patterns of operation, namely constant, reactive and pilot jamming. First, the observations were performed inside an anechoic chamber and, finally, outdoor, in two relevant outdoor scenarios, a straight road in an open space and a dense building scenario.

date/time of measurement start: 2011-11-01

date/time of measurement end: 2012-03-09

collection environment: For the indoors, we used the anechoic chamber available at room I-106 at FEUP. For the outdoor measurements, we carried out experiments in two scenarios: a straight road in an open area with no surrounding buildings, i.e., a nearly non-dispersive environment, and a crossroad surrounded by buildings, i.e., a highly dispersive environment. We refer to the first case as open space scenario while the second scenario is referred to as university campus scenario. In neither environment there was significant movement of objects besides the transmitter and receiver involved in the experiment. For the open space scenario, the measurements were performed in an open field parking lot near the seafront of Leça da Palmeira, Porto, while in the university campus scenario they were performed in the FEUP campus.

network configuration: For the measurements, we used the Wireless Open-Access Research Platform (WARP) boards for implementing the jammer. The WARP boards provide an 802.11-like OFDM design on FPGA and a 10MHz bandwidth 802.11a/g RF transceiver, which allows transmission at frequencies up to 5.875 GHz, hence, covering 802.11p channels 172 and 174. For both the transmitter and receiver, we used NEC Linkbird 802.11p connected to a laptop Asus Eee PC running a java application to generate traffic (transmitter) and to retrieve information from the packets received at the linkbird (receiver). All reported measurements were carried out at 5.86 GHz, which corresponds to the lowest channel (Ch.172) of the frequency band allocated to 802.11p communications and is meant for public safety communications. The omni-directional antennae used in our measurements are designed to work at the 5.0-6.0 GHz band and yield a 6 dBi gain. In every experiment, the transmitter sends packets with 17.48 dBm of transmit power, at a data rate of 6 Mbps (QPSK 1/2), payload length of 100 Byte and at 100 packets per second. For the constant and reactive jamming profile, the signal has 16.75 dBm, lasts for 64 microseconds and between two consecutive transmission, there is a unavoidable preparation time of 10 microseconds. The reactive jamming profile has a energy detection threshold of -75 dBm, a detection time of the reactive profile lasts 1.2 microseconds and a total reaction delay is uniformly distributed between [11.2-21.2] microseconds. Regarding the pilot jammer profile, it has a transmitted power of 2.42 dBm, a duration of 2.04 ms and the preparation time of 10 microseconds.

data collection methodology: Log files from a java application was used along with the traces generated by the two linkbirds (plus the gps readings, for the outdoor measurements) to assess the impact of the jammer.

Tracesets

chamberpathloss

Traceset collected in the anechoic chamber to calculate the pathloss between Transmitter and Receiver, Jammer and Transmitter, and Jammer and Receiver.

• files: uportorwthaachen-vanetjamming2012.tar.gz, jammer_rx.tar.gz, tx_jammer.tar.gz, tx_rx.tar.gz
