Mobile IPv6 (MIPv6) is considered inefficient to support mobility due to larger handover delay and signaling overhead. Therefore, Hierarchical MIPv6 (HMIPv6) is designed by introducing a Mobile Anchor Point (MAP) in the MIPv6 architecture. The MAP considerably drops the handoff delay and signaling load for mobility management in IPv6. The Three Layered MIPv6 (TLMIPv6), the focus of this paper, is influenced by the benefits of placing MAPs for efficient mobility management. In this model, three MAPs are placed in the architecture to reduce signaling cost and handoff latency. These MAPs are placed hierarchically in a tree like architecture, and the movement of nodes is coordinated by different MAP based on nodes’ movement patterns. The behavior of the proposed model is simulated under various traffic scenarios and mobility conditions and compared with MIPv6 and HMIPv6 and Flow Based Distributed Mobility Management (FBDM) protocols. The results depict that when users are less mobile or confined their movements to a small geographical area, the proposed TLMIPv6 outperforms MIPv6, HMIPv6, and FBDM in handoff latency and signaling costs. Some suitable application scenarios for adopting TLMIPv6 are also mentioned at the end of the paper. The future scopes of the work are outlined.

由于更大的切换延迟和信令开销，移动IPv6（MIPv6）被认为无法有效地支持移动性。因此，通过在MIPv6体系结构中引入移动锚点（MAP）来设计分层MIPv6（HMIPv6）。MAP大大降低了IPv6中用于移动性管理的切换延迟和信令负载。本文的重点是三层MIPv6（TLMIPv6），受放置MAP进行高效移动性管理的好处的影响。在该模型中，在架构中放置了三个MAP，以减少信令成本和切换等待时间。这些MAP分层地放置在类似树的体系结构中，节点的移动由基于节点的移动模式的不同MAP进行协调。该模型的行为在各种流量场景和移动性条件下进行了仿真，并与MIPv6和HMIPv6以及基于流的分布式移动性管理（FBDM）协议进行了比较。结果表明，当用户的移动性降低或将其移动限制在较小的地理区域时，建议的TLMIPv6在切换延迟和信令成本方面优于MIPv6，HMIPv6和FBDM。本文结尾还提到了一些适合采用TLMIPv6的应用场景。概述了工作的未来范围。本文结尾还提到了一些适合采用TLMIPv6的应用场景。概述了工作的未来范围。本文结尾还提到了一些适合采用TLMIPv6的应用场景。概述了工作的未来范围。
