Car-to-Car Communication (C2CC) is an important research and future application topic which is getting increasing attention from all major car manufacturers. Direct communication between individual vehicles can significantly increase passenger safety and comfort. An example is the exchange of traffic information, as in the novel Self-Organizing Traffic Information System (SOTIS), which has been proposed in the FLEETNET project. SOTIS is a decentralized information system which uses a technique called Segment-Oriented Data Abstraction and Dissemination (SODAD) to solve two of the most pressing challenges for C2CC: required penetration and scalability. While most of the envisioned applications for C2CC require a relatively large ratio of equipped vehicles, SOTIS provides significant benefit even if only a small fraction of all vehicles is equipped, e.g. as in the phase of market introduction. In order to demonstrate the SOTIS idea and as a proof-of-concept, a SOTIS prototype has been implemented based on commercially available standard hard- and software. This article describes the design and implementation of the prototype and outlines first experimental results.
