Abstract

Vehicular ad-hoc networks (VANETs) are promising means for distributed automotive applications. In addition to developing new communication protocols for VANETs, the widespread use of general purpose wireless network standards like WLAN IEEE 802.11a/b/g raises the need to investigate whether these networks are suitable for VANETs. The results from such experimental studies allow to introduce better simulation models and to evaluate the appropriateness of analytical models for wireless networks. This work proposes a structured, scenario-based approach for measuring wireless networks in motion, which can easily be exploited by simulations. By applying the approach to IEEE 802.11g ad-hoc networks, experiments and results are described. The signal strength has been investigated for all mobility scenarios and is presented for the most significant cases as well as compared to the free space loss formula of electromagnetic waves. Furthermore, the throughput and packet loss are studied for traffic bursts while moving.
