With the greatly increased number of vehicles in our society, a lot of new issues concerning the transportation arise. Among them, traffic safety is one of the hottest topics. To improve traffic safety, the decentralized communication network for Inter-Vehicle Communication (IVC) system has drawn great attention all over the world in recent years. On the basis of the principle theories and frames, various ideas using all kinds of communication technologies have been proposed to make it practically suitable for real application and enhance the system performance.

This paper investigated the basic structure of the IVC system and performance evaluation of ARQ in this system. Based on the basic application environment, the system model was constructed and simulation parameters were defined. A simulation idea called 'Snapshot' was proposed to turn a dynamic real system to a static system suitable for modeling.

Automatic Retransmission Request (ARQ), as a main technology, was examined in this paper. The simulation results about the system performance with ARQ and without ARQ have been provided, along with the detailed analysis about their respective features and performance comparison. Additionally, to enhance the system performance, two improvement methods are proposed. Their functions are simulated and analyzed.

In the last section, several directions for the future work are pointed out based on the research work in this thesis.
