collection environment

For the outdoor measurements, we carried out experiments in a rural area located in the periphery of Aachen in Germany. The area has two perpedicular roads. A main road that has a length of 600 m and a 120 m long side road. The line-of-sight along the main road (about 300 m) is shorter than its total length due to a slight descending slope of that road. Furthermore, the area between main road and side road exhibits a slight elevation of the ground that can block line-of-sight along the diagonal path between both roads. The amount of traffic in the area is negligible with only few sporadic cars. This open space scenario offers a low dispersive propagation environment, as there are no obstacles or buildings between or surrounding the vehicles.

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. The signal from every jamming profile has 16.75 dBm. The constant jamming signal is characterized by a 2.71 ms ON phase and a 10 microseconds OFF phase. The periodic jamming signal is characterized by a 64 microseconds ON phase and a 10 microseconds OFF phase. The reactive jamming (12 microseconds, 500 microseconds) profile has an energy detection threshold of -75 dBm, a reaction delay of 12 microseconds, and lasts for 500 microseconds. The reactive jamming (40 microseconds, 500 microseconds) profile has an energy detection threshold of -75 dBm, a reaction delay of 40 microseconds, and lasts for 500 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, assess the impact of the jammer.
