Service Discovery and Service Access in Wireless Vehicular Networks

Robust and reliable service architectures must be designed to guarantee the success of future vehicular networks. This paper addresses service provisioning elements such as communication service models, service discovery and service access intended for vehicular environments. We propose a secure service access architecture based on the concept of district domains which are entities responsible for dispatching session parameters to on-demand users. The service architecture comprises the presence of public and private certificate authorities, session managers, policy entities, accounting and banking modules. The purpose of this architecture is to facilitate the delivery of secured information services offered at the roadside infrastructure.
