Routing schemes for switch-based in-vehicle networks

In this paper, we study in-vehicle digital network systems. We propose a switch-based architecture for in-vehicle networks and focus on the critical related issue: routing schemes. We note that in-vehicle networks are fundamentally different from many other switch-based networks (e.g., the Internet). This is because within an in-vehicle network, messages are not unicast or multicast as in the Internet, but many-to-many cast. We analyze several routing schemes. We investigate if routing schemes that have already been proposed for Internet-like networks, may be feasible for our in-vehicle networks. We also propose a new algorithm that is specifically designed for many-to-many cast messages as an initialization for further research on routing schemes for switch-based in-vehicle networks.
