Provides an up-to-date, in-depth look at the currentresearch, design, and implementation of cooperative vehicle safetycommunication protocols and technology Improving traffic safety has been a top concern fortransportation agencies around the world and the focus of heavyresearch and development efforts sponsored by both governments andprivate industries. Cooperative vehicle systems—which usesensors and wireless technologies to reduce trafficaccidents—can play a major role in making the world's roadssafer. Vehicle Safety Communications: Protocols, Security, andPrivacy describes fundamental issues in cooperative vehiclesafety and recent advances in technologies for enabling cooperativevehicle safety. It gives an overview of traditional vehicle safetyissues, the evolution of vehicle safety technologies, and the needfor cooperative systems where vehicles work together to reduce thenumber of crashes or mitigate damage when crashes becomeunavoidable. Authored by two top industry professionals, the book: Summarizes the history and current status of 5.9 GHz DedicatedShort Range Communications (DSRC) technology and standardization,discussing key issues in applying DSRC to support cooperativevehicle safety Features an in-depth overview of on-board equipment (OBE) androadside equipment (RSE) by describing sample designs to illustratethe key issues and potential solutions Takes on security and privacy protection requirements andchallenges, including how to design privacy-preserving digitalcertificate management systems and how to evict misbehavingvehicles Includes coverage of vehicle-to-infrastructure (V2I)communications like intersection collision avoidance applicationsand vehicle-to-vehicle (V2V) communications like extendedelectronic brake lights and intersection movement assist Vehicle Safety Communications is ideal for anyone workingin the areas of—or studying—cooperative vehicle safetyand vehicle communications.

Vehicle Safety Communications

The advent of multimedia technology is creating a number of new problems in the fields of computer and communication systems. Perhaps the most important of these problems in communication, and certainly the most interesting, is that of designing networks to carry multimedia traffic, including digital audio and video, with acceptable quality. The main challenge in integrating the different services needed by the different types of traffic into the same network (an objective that is made worthwhile by its obvious economic advantages) is to satisfy the performance requirements of continuous media applications, as the quality of audio and video streams at the receiver can be guaranteed only if bounds on delay, delay jitters, bandwidth, and reliability are guaranteed by the network. Since such guarantees cannot be provided by traditional packet-switching technology, a number of researchers and research groups during the last several years have tried to meet the challenge by proposing new protocols or modifications of old ones, to make packet-switching networks capable of delivering audio and video with good quality while carrying all sorts of other traffic. The focus of this book is on HeiTS (the Heidelberg Transport System), and its contributions to integrated services network design. The HeiTS architecture is based on using the Internet Stream Protocol Version 2 (ST-II) at the network layer. The Heidelberg researchers were the first to implement ST-II. The author documents this activity in the book and provides thorough coverage of the improvements made to the protocol. The book also includes coverage of HeiTP as used in error handling, error control, congestion control, and the full specification of ST2+, a new version of ST-II. The ideas and techniques implemented by the Heidelberg group and their coverage in this volume apply to many other approaches to multimedia networking.
