A new in-vehicle network is developed and elaborated. The new protocol hierarchy aims at an ad hoc integration of typical in-vehicle networks, like CAN, IEEE 1394 and others. Therefore several communication protocols are developed. First an overall communication scheme needs to be available to allow end-to-end communication. This is done similar to OSI Layer 5, as session based communication. Sessions allow transitive communication paths without interruption. With this, an ad hoc behavior of the network is supported. Ad hoc changes are typically caused by power management and user behavior. Devices and applications can be connected, disconnected, turned on and off. This causes changes in the network topology as well as on higher layers in the availability of services. Automatic communication mechanisms are developed to detect changes of the network topology and in the available services. The result is a passive context aware system, which aggregates and classifies the available services and network resources. It provides a standardized interface for applications to find their peers. Ad hoc movements and changes are hidden to the applications as long the requested services are available.
