A new network clustering concept for foresighted driving applications is introduced, taking into account the specific requirements for highly dynamic intervehicle networks. Considering initially low system penetration in the market, the concept includes so-called message relay boxes without backbone network connection for temporary roadside storage of messages. The article differentiates between moving and quasi-stationary applications and explains how clusters tied to specific geographic locations will lead to even more complicated mechanisms for topology management in clustered ad hoc networks. A proposed message handling algorithm for cluster establishment shows the complexity needed to guarantee overall data consistency and network reliability as required for safety-relevant cooperative systems.
