摘要：Seamless handover scheme with low latency and packet loss is pursued by numerous researchers. For this, Hierarchical Mobile IPv6 (HMIPv6) has been introduced as a way of constructing efficient wireless networks. But due to its choice of the fixed farthest available MAP as forwarding agent which may bring problems such as load balance or overload to the MAP in network with multiple MAPs, besides, HMIPv6 still can't meet requirements of seamless handover. In this paper, we first construct a new topology model and give a detailed introduction on it through studying of HMIPv6 macro handoff. then we adopt a more flexible and scalable method of MAP selection to alleviate the problems aforementioned and utilize fast handover mechanism with serial duplicate address detection (SDAD) to improve the handover performance especially when the macro handoff occurred. Afterwards, theoretical analysis is provided to evaluate performance of our proposed scheme. At last, simulation results are given to validate that our proposed scheme is more superior and effective than the standard HMIPv6 scheme. © 2011 IEEE.
