The Future Vision Distribution Service (FVDS) (Sato, et al., 2004) is an innovative video delivery service concept based on the Internet ITS (Intelligent Transport System) area, and Source Mobility Support Multicasting (SMM) (Sato, et al., 2004) consists of new multicasting techniques needed to realize FVDS. However, FVDS and SMM lack sufficient application-level protocols to manage preceding and following vehicles on the same route, and have a drawback of topological constraints in the access network to accommodate micro-mobility. To solve these problems, this paper presents two new protocols. The Mobile Vehicle Management (MVM) protocol is an application-level protocol that discovers a preceding vehicle on the same route and provides its multicast address to following vehicles by using information from the global positioning system (GPS) and a route-guiding function. The Self-Organizing Tree (SOT) protocol is a network-level protocol for use in the access network that organizes radio base-stations into a logical tree topology in a self-forming and self-healing manner. This eliminates the topological constraints and provides the network with robustness against failures and flexibility for network design. To show how these protocols further the implementation of FVDS and SMM, this paper also gives details of a software implementation model for each network node system; specifically, we have designed a software architecture, composition elements for each protocol and their relations, and internal state-machines for each element.
