VAS

Cooperating embedded systems

The VAS project is a platform for research in the areas of cooperating embedded systems, vehicular ad-hoc networks (VANETs), wireless sensor networks and wireless digital communication. Research within VAS is conducted at the Center for Research on Embedded Systems (CERES) in cooperation with partners from industry.

The purpose of the VAS project is to provide an application scenario for research in the area of vehicle alert systems at three different levels: application, network and link layer.

• At the application layer, the system must be able to handle heterogeneous nodes in secure and scalable ways.
• At the network level, routing and addressing protocols face similar challenges due to high vehicle mobility.
• At the link level, the high velocities and dynamic conditions impose strict timing constraints. Reliable connections must be formed using efficient coding and modulation methods for timely delivery of information.

VAS aims to use vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications to provide different types of warning messages. The main focus of the project is on communication and in particular the lower layers of the communication stack will be investigated. 

The VAS project is seen as a complement to the CVIS project in general, and to the COMM sub-project in particular. The VAS project could provide CVIS with simulation results on scalability of CALM M5 communication. VAS could also help reach and enforce the goals of the DEPN sub-project by ensuring that, for example, CALM M5 and vehicle alert applications are fundamentally deployable and integrate properly with other CVIS applications. Further, VAS can provide input to DEPN by verifying that the derived road maps on how to migrate from today’s situation to a future with widespread CVIS equipment involves scalable solutions.
