Resource Management for Third-Generation Telematics Systems

Due to the safety-related nature of in-vehicle systems and the increasing complexity of distributed telematics software services, protocols, and communications mechanisms, the need exists for a comprehensive, extensible approach to manage and prioritize applications and resources. The characteristics for such an approach include predictability, support for the user experience, error handling and preemptive correction, and support for unknown future applications and capabilities. This paper provides a structure for addressing telematics services, discusses the characteristics required for application and communications resource prioritization and management, and describes an extensible approach for managing complex interactions in current and future telematics systems.
