在无线网络中，系统生存性是提供服务质量（QoS）的最重要问题之一。然而，由于归属代理（HA）或移动的锚点（MAP）的故障导致服务中断，分层移动的IPv6（HMIPv 6）仅具有弱生存性。在本文中，我们提出了鲁棒的分层移动的IPv6（RH-MIPv 6），它提供了容错性和鲁棒性在移动的网络。在RH-MIPv 6中，移动的节点（MN）同时向两个不同的MAP（主MAP和辅MAP）注册主（P-RCoA）和辅（S-RCoA）区域转交地址。我们开发了一种机制，使移动的节点或对端节点（CN）检测到主MAP的故障，并改变其附件从主到辅助MAP。通过这种恢复过程，可以减少故障恢复时间。分析评估表明，RH-MIPv 6具有更快的恢复时间比HMIPv 6，我们也通过模拟显示类似的分析结果。因此，RH-MIPv 6的恢复时间比HMIPv 6快60%。
In wireless networks, system survivability is one of the most important issues in providing quality of service (QoS). However, since failure of home agent (HA) or mobile anchor point (MAP) causes service interruption, the hierarchical mobile IPv6 (HMIPv6) has only weak survivability. In this paper, we propose robust hierarchical mobile IPv6 (RH-MIPv6), which provides fault tolerance and robustness in mobile networks. In RH-MIPv6, a mobile node (MN) registers primary (P-RCoA) and secondary (S-RCoA) regional care of addresses to two different MAPs (primary and secondary) simultaneously. We develop a mechanism to enable the mobile node or correspondent node (CN) to detect the failure of primary MAP and change their attachment from the primary to secondary MAP. By this recovery procedure, it is possible to reduce the failure recovery time. Analytical evaluation indicates that RH-MIPv6 has faster recovery time than HMIPv6 and we also show through simulation as like analytical result. Consequently, RH-MIPv6 shows about 60% faster recovery time compared with HMIPv6.
