Abstract：To solve the long handover latency of mobile network in NEtwork MObility (NEMO) Basic Support (NBS)，this paper proposed a scheme for NEMO within PMIPv6. Then an improved handover procedure for this scheme was suggested. The proposed scheme, which decreased the number of handover messages transmitted on wireless link and in advance set up the tunnel to forward packets, achieved fast handover of mobile network. Compared with NBS’s handover procedure, the analytical results show that the standard handover procedure and fast handover procedure of the proposed scheme decrease handover latency by 56.55% and 58.63% respectively.
