Performance measurement of car-to-car ad-hoc networks in the real world

초록

This paper shows the performance of car-to-car ad-hoc networks in the real world. Actually there are many irregular driving environments, so we have established some scenarios about inter-vehicle communications can happen in our actual life. And we have measured the transmission characteristics such as throughput, delay and packet loss rate of the system for each case. We have installed laptops with IEEE 802.11b wireless LAN and software for the ad-hoc network and packet transmission at each car. A test-bed has been implemented to support TCP/UDP packet transmission on wireless ad-hoc environment such as AODV (Ad-hoc On Demand Distance Vector) and OLSR (Optimized Link State Routing). Scenarios we have used in this experiment present which algorithm of ad-hoc routing and transmission is suitable in real driving environment and how performance metrics change according to different circumstances.
