Abstract
In this paper we present the design of a vehicular computing platform starting from hardware up to the application layer. In particular, we present a network protocol stack consisting of several new, vehicle-specific layers such as (i) Data Validation and Caching, (ii) Store and Forward Message Routing, (iii) In-Network Processing, and (iv) a Location-aware Publish-Subscribe framework, which uses GPRS/3G links to efficiently route high-priority messages between disconnected ad-hoc networks. We point out the key issues and challenges that need to solved in order to realize the dream that is vehicular computing.
