In this paper, we propose a new mobility management network scheme which is called i2FP (Industrial Intelligent Fast Proxy IPv6) to solve the existing problem and improve the signaling efficiency for industrial networks such as smart factory networking. To enable MN (Mobile Node) to move other network in one domain, i2FP employs three network entities which are SFA (Smart Factory Anchor), FAG (Factory Access Gateway) and MN from PMIPv6 (Proxy Mobile IPv6) with extension concept. In i2FP, The three network entities can reduce the handover delay time of MNs. Also, i2FP uses an IP header swapping mechanism to avoid the traffic overhead and improve the throughput of network. To evaluate the performance of i2FP, we measure new framework of i2FP, HMIPv6(Hierarchical Mobile IPv6) and PMIPv6 which are legacy protocols of local mobility management. Therefore, we show the i2FP has good performance than other network schemes in terms of the total cost.
