Abstract

Today users are getting used to have many heterogeneous devices available in their surroundings. This opens great opportunities to build pervasive communication environments. Pervasive communications are usually user-centric in nature, as they should target sessions to users rather than their specific devices. Mobility is a key issue in such context: users often move and that implies different devices and networks to become available to them dynamically. As a matter of fact, terminal handovers and session migrations could negatively impact the enjoyment of multimedia content in such scenarios. In this paper, we propose a user-centric mobility framework for multimedia interactive applications. To this aim, we implement the concept of Personal Address, that is a network identifier assigned to users. Our mobility framework exploits this concept to accounts for all aspects of mobility. Moreover, we describe our deployment for Voice-over-IP sessions; finally, we report the results from our experimental testbed.
一个以用户为中心的移动框架,用于多媒体交互应用程序
今天,用户已经习惯了在他们的环境中使用许多异构设备。这为建立普及的通信环境提供了巨大的机会。普及通信本质上通常以用户为中心,因为它们应该将会话定位于用户而不是特定的设备。在这种情况下,移动性是一个关键问题:用户经常移动,这意味着他们可以动态地使用不同的设备和网络。事实上,在这种情况下,终端切换和会话迁移可能会对多媒体内容的享受产生负面影响。在本文中,我们提出了一个以用户为中心的多媒体交互移动框架。为此,我们实现了个人地址的概念,即分配给用户的网络标识符。我们的机动性框架利用这一概念来解释机动性的各个方面。此外,我们描述了我们对ip语音会话的部署;最后,我们报告了实验试验台的结果。
