چکیده
This paper provides an overview of reliability issues in vehicular ad hoc networks (VANETs) for safety-related applications. First, IEEE 802.11p based DSRC system, communication environment, and applications on safety related services are introduced. The factors affecting the reliability of safety services provided by VANETs are identified. Second, the features and requirements of VANETs for safety applications are discussed. Third, the relevant reliability issues are raised, and the reliability metrics are defined for the evaluation of such systems. Fourth, the analytical models from recent literature for both one-hop message broadcast and multi-hop broadcast are listed, described, and compared. Finally, having summarized drawbacks of the current analytical models for safety applications in VANETs, some potential topics for future research are suggested.
