A number of multicast and mobile routing techniques have been developed for IP networks. However, multicasting that supports the mobility of the source host has not received sufficient attention. This paper proposes 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 caused by a source movement. SMM is based on a new concept of constructing multicast trees over Cellular IP ' based networks, in which a source point tree and a rendezvous point tree are combined into one multicast tree. It also provides wide operability by partitioning the network and confining protocol uniqueness and topological constraints within the local access networks. This paper gives an overview of the SMM technique and protocol descriptions, and presents the results of numerical analyses to minimize the tree reconstruction overhead due to a source movement.
