由于需求多媒体内容的增加和移动的设备数量的增加，移动的互联网数据业务在过去几年中经历了指数增长。IP级的无缝移动性支持被设想为关键架构要求，以便处理对数据的不断增长的需求并有效地利用过多的不同无线接入网络。目前工业界和学术界的努力旨在将移动性管理协议向更加分布式的操作发展，以解决完全集中式方法的缺点。然而，分布式解决方案面临着几个挑战，可能会导致较低的性能，这可能会影响实时和多媒体应用程序。在本文中，我们进行了分析和模拟评估的主要集中式和建议的分布式移动性管理（DMM）解决方案。我们的研究结果表明，在某些情况下，当用户以高速移动和/或当移动的节点正在运行持久的应用程序，DMM方法产生高信令成本和长切换延迟。
Mobile Internet data traffic has experienced an exponential growth over the last few years due to the rise of demanding multimedia content and the increasing number of mobile devices. Seamless mobility support at the IP level is envisioned as a key architectural requirement in order to deal with the ever-increasing demand for data and to efficiently utilize a plethora of different wireless access networks. Current efforts from both industry and academia aim to evolve the mobility management protocols towards a more distributed operation to tackle shortcomings of fully centralized approaches. However, distributed solutions face several challenges that can result in lower performance which might affect real-time and multimedia applications. In this paper, we conduct an analytical and simulated evaluation of the main centralized and proposed Distributed Mobility Management (DMM) solutions. Our results show that, in some scenarios, when users move at high speed and/or when the mobile node is running long-lasting applications, the DMM approaches incur high signaling cost and long handover latency.
