In this paper, aiming at the problems of handover existing in the Fast Hierarchical Mobile IPv6(FHMIPv6)protocol in wireless sensor networks, an Improved Fast Hierarchical Mobile IPv6(I_FHMIPv6) protocol is presented.Performance analysis and simulation experiments presented in this paper show that this proposal outperforms the current schemes on aspect of handover delay and throughput.%针对快速分级移动IPv6协议应用在无线传感器网络当中存在的问题,提出了一种改进的快速分级移动IPv6切换方案,该方案能够减少切换延时、提高吞吐量.仿真结果表明,该方案是有效可行的.
