    • Many researches on network mobility management nowadays have been done to support movement of a mobile network, including the network mobility basic support protocol (NEMO BSP) [7], the reverse routing header (RRH) [24], and the hierarchical mobile network binding (HMNB) [12]. However, NEMO BSP has many limitations, e.g., pinball routing problem, lack of intra-domain data communication, etc. As for RRH, it suffers from a binding update (BU) storm when the root mobile router (MR) handover occurs. Likewise, a lot of signaling overheads and a long handover delay occur in HMNB. To support route optimization and intra-domain data communication without a BU storm, a too long handover delay, and too many signaling overheads, a solution using subtree list and routing tables is proposed in this paper. This solution uses subtree list tables and a distributed manner to inform all home agents (HAs) associated with the care of address (CoA) of the new root-MR to avoid a BU storm with fewer signaling overheads and a shorter handover delay. Applying the derived analytical results, we demonstrate that the proposed solution can outperform NEMO BSP, RRH, and HMNB.
