network type

802.11 ad-hoc

collection environment

The experiments were conducted in the northwest sector of Atlanta, GA along I-75 between Exit 250 and Exit 255 as shown in the figure in the README files in the traces. This section of I-75 corridor has five regular lanes in addition to one HOV lane in most parts of the study area. Vehicle traffic in the opposite directions is separated by a concrete median barrier. All the experiments were conducted between 2pm and 5pm under non-congested traffic conditions and non-inclement weather conditions.

network configuration

For the experiments, laptop computers running Red Hat Linux 9, an ORINOCO 802.11b gold card with a 2.5dB omni-directional external antenna placed on the roof of the vehicle, and a Garmin 72 GPS receiver (with WAAS correction). The wireless cards configured in IBSS ad-hoc mode with power management turned off and a fixed data rate. The GPS reports latitude, longitude, speed, and heading of the vehicle every 2 seconds. The location information reported by GPS has an accuracy of 5-7 meters. We obtained location information every second through interpolation. All experiments were conducted using broadcast at 2Mbps that allows us to explore basic communication performance because there is no RTS/CTS/ACK and retransmissions.

data collection methodology

IPerf, a network performance measurement tool was used along with the GPS readings to in conjunction with GPS readings to measure network performance. Both sender and receiver log time, location, velocity (from GPS), data packets received / sent, and signal quality.
