Abstract

In this paper, VANET applications have been classified according to their purpose. Furthermore, a clean-slate architecture specifically designed for VANETs has been introduced. The proposed non-layered context-aware ubiquitous architecture adapts dynamically to changes, is oriented to services (VANET applications) and has a flexible structure. The vehicle and environmental context-aware information as well as the VANET communication characteristics are designed for the proper operation of the applications. In addition, the performance of Automatic Repeat Request and Forward Error Correction (FEC) block codes with respect to the throughput efficiency has also been analyzed for a VANET following the proposed clean-slate architecture. The numerical results show that the proposed clean-slate architecture outperforms the traditional layered architecture with respect to the throughput efficiency for both error control schemes. FEC block codes are able to maintain high throughput efficiency over longer distances because the hop length extension technique is applied.
