Abstract:

The Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol, but the transmission efficiency is affected by the requirement that all the data packets   traverse the Local Mobility Anchor. In this paper, a novel localized routing scheme is proposed. Based on various topology infrastructures in the actual applied scenario, the appropriate LR-initiator is selected dynamically and the decision rules of LR are made reasonably. In addition, the signaling transmission is optimized in order to reduce the protocol overhead. Theoretical analysis and simulation results indicate that the proposed scheme can obviously shorten the response time of LR compared with a classical protocol called LRP, and overcome the defect that the solution of LR cannot be provided in some special scenario when using LRP.
