In this paper, we propose an innovative information delivery service on intelligent transport systems (ITS), which enables users to see their future vision delivered from users at further points along the route. This service requires special multicast and mobile routing schemes. We have developed a source mobility support multicast (SMM) technique that guarantees consecutive communication in high-speed mobile environments and minimizes the overhead in reconstructing multicast trees, which is caused by a source movement. SMM is based on a new concept where multicast tree is constructed over cellular IP network according to A. G. Valko (1999), in which a source point tree and a rendezvous point tree are combined into one multicast tree. SMM provides wide operability by partitioning the network and confining protocol uniqueness and topological constraints within the local access networks. This paper shows our design of SMM architecture and its detail protocols.
