| In comparison to other communication
networks, Vehicular Ad-hoc Networks (VANETs) have unique
requirements with respect to applications, types of
communication, self-organization and other issues. In order to
meet these requirements, the structuring of functionalities into
protocols and their interaction must be re-thought. The
traditional approach of decomposition of functionality into
protocol layers (layered approach) and a protocol design
specifically tailored to the needs of VANETs (un-layered
approach) leads to two extreme and opposed manifestations of a
potential VANET protocol architecture. From these two extreme
approaches we derive a stack-based VANET protocol architecture
that combines the strengths of both. Among the key features of
this protocol architecture are VANET-specific protocol layers, a
staircase approach for interaction among layers, and the use of
an information connector for the exchange of cross-layer
information using the publisher/subscriber pattern. This protocol
architecture provides a clear modular structure with flexibility
for protocol interaction and information exchange at a reasonable
complexity. |
