Network mobility solution based on predictive fast handover in PMIPv6 domain

In this paper, a novel NEtwork MObility(NEMO) solution based on predictive fast handover is proposed to solve the problem of long handover delay and lack of effective inter-domain handover scheme in Proxy Mobile IPv6(PMIPv6) network. With the help of L2 scheme ,NEMO can perform pre-handover before getting registered so that relevant information is acknowledged in advance. Inter-domain handover is supported by extending signaling messages to make entities communicate between different domains. The packet loss problem is eliminated by introducing double buffering scheme. Analysis and simulation shows that this solution can reduce the delay during handover and improve communication efficiency.
