在基于 IP 的移动方案和蜂窝网络中，移动支持依赖于向移动节点位置转发流量和从移动节点位置转发流量的集中式方法。为了克服这些移动性方法的固有局限性，例如集中式功能引起的灵活性问题和可扩展性问题，我们在（1）中提出了一种新的分布式动态方法，用于管理接入节点级别的移动性。本文通过模拟的方式进一步评估了这种新的 DMA（动态移动锚定）方案。因此，我们比较并进一步分析了 DMA 和典型的集中式方案在向无线网络中移动的用户提供实时流量时所实现的切换和流量延迟。我们的结果表明，与更传统的方案（例如移动 IP 及其各种优化）相比，DMA 具有巨大的优势。我们未来的工作将主要解决 DMA 对各种网络环境的适应性问题。
In both IP based mobility schemes and cellular networks, mobility support relies on centralized approaches forwarding traffic towards and from mobile nodes location. In order to overcome the inherent limitations of those mobility approaches such as flexibility concerns and scalability issues caused by centralized functions, we proposed in (1) a new distributed and dynamic approach for managing mobility at access nodes level. This new DMA (Dynamic Mobility Anchoring) scheme is further evaluated in this article by means of simulations. Thus, we compare and further analyze the achieved handover and traffic delays for both DMA and a typical centralized scheme when delivering real-time traffic to a user moving in a wireless network. Our results show promising benefits of DMA compared to more traditional schemes such as Mobile IP and its various optimizations. Our future work will mostly address the adaptability of DMA to various networking environments.
