| 摘 要： | 由于无线局域网(WLAN)IEEE802.11协议不能解决移动节点的三层漫游问题,介绍了WLAN与移动IP结合的解决方案。由于上述方案存在切换延时长、不支持微移动性等缺陷,研究了分层移动IP技术,并对分层移动IP进行了改进,提出了一个多GFA分层移动IP(MG-HMIP)模型,并详细介绍了MG-HMIP模型的注册机制和MN选择GFA的机制。最后,给出了MG-HMIP与WLAN结合的模型。这个改进的方案不仅解决了WLAN与传统的MobileIP结合所存在的切换延时长、频繁切换等问题,而且增强了分层移动IP的网络健壮性。

| Abstract: | Since IEEE 802.11 protocol can not resolve the third-layer-roaming problem of mobile nodes,a integrated scheme of WLAN and mobile I Pis introduced.However,this scheme has some limitations,such as longer handoff latency and non-support of Micro-Mobility.Therefore,the hierarchical mobile I Pis researched and improved,and a model of Multiple GFA Hierarchical Mobile I P(MG-HMIP)is proposed,in which both the register mechanism of the MG-HMI Pmodel and the mechanism of MNs choosing the GFA are introduced in detail.And finally,a model of integration of MG-HMI Pand WLAN is presented.This improved scheme not only resolves the problem of the integration of WLAN and conventional mobile IP,such as the longer handover latency,frequent handover,etc,but also enhances the robusticity of the hierarchical mobile I Pnetworks. |
