ITS solutions require distributing content to vehicles traveling on streets and highways. This is becoming a more natural evolution in response to the pervasiveness of wireless devices in vehicles and urban areas. We propose a hierarchical architecture for ITS content delivery. The architecture utilizes the concepts and mechanisms of service-orientation to address the stringent requirements of vehicular requirements. The architecture also efficiently organizes services based on their location relevancy. We define algorithms and message structure used within the architecture to manage content services and efficiently delivery them to vehicles. Those algorithms include content service addition, updating, deletion, discovery, consumption and maintenance across different infrastructure nodes. We evaluate the benefits of the proposed scheme using OMNET++ simulator. Our results show that the architecture efficiently delivers content to vehicle traveling at moderate speeds as well as separated by average separation distances. Outside of these ranges, and due to extensive workloads of service delivery requests or requests to maintain delivery session, the communications overhead of the architecture increases decreasing its efficiency.
