我们提出并研究了互联网协议版本6（IPv6）启用移动框架，以提高用户的移动性体验在异构无线网络。该框架考虑了传统的IP网络基础设施，基于IPv6的移动性支持，多宿主，业务流透明的路由器和平面/动态的移动性策略执行，以保证服务质量（QoS）和体验质量（QoE）与无处不在的连接。使用网络移动性（NEMO），我们可以垂直地提供跨WiFi、WiMax和UMTS系统的灵活网络集成机制。灵活的方法克服了不同的网络接入拒绝时，节点移动使用两个操作的限制：策略强制切换管理和动态切换实现。本文介绍了解决方案背后的设计原理，介绍了一个实验测试平台和仿真模型，验证移动相关的服务性能，并讨论了我们的研究结果。
We propose and investigate the Internet Protocol version 6 (IPv6) enabled mobility framework to improve the user mobility experience in heterogenous wireless networks. The framework considers the traditional IP network infrastructure, IPv6 based mobility support, multihoming, traffic flow transparent handovers and flat/dynamic mobility policy enforcement to guarantee the Quality of Service (QoS) and Quality of Experience (QoE) with ubiquitous connectivity. Using Network Mobility (NEMO) we can provide a flexible network integration mechanism across WiFi, WiMax and UMTS systems vertically. The flexible approach overcomes the limitation of different networks access denial when nodes move using two operations: Policy enforced handover management and Dynamic handover implementation. The paper describes the design rationale behind the solution, introduces an experimental testbed and simulation models, validates mobility related services performance, and discusses our research findings.
