移动计算环境的特征是其支持基础设施的显著且快速的变化，特别是从其底层通信信道可用的服务质量(Qos)。能够在这些环境中运行并利用不断变化的服务质量的应用程序需要分布式系统支持平台。此类平台中的当前最先进技术试图提供反映其固定网络起源的同步面向连接的编程范例。在本文中，我们认为这些范例不能很好地适用于移动环境中的操作，而是提出了一种基于元组空间通信范例的新平台Libo。文中给出了Libo的设计，并给出了两个原型的具体实现。还讨论了利用该平台对一些现有的自适应移动应用程序进行重新设计。
Mobile computing environments are characterised by significant and rapid changes in their supporting infrastructure and, in particular, in the quality-of-service (QoS) available from their underlying communications channels. Applications which can operate in these environments and take advantage of changing QoS require distributed systems support platforms. The current state-of-the-art in such platforms attempt to provide synchronous connection-oriented programming paradigms reflecting their fixed network origin. In this paper we argue that these paradigms are not well suited to operation in a mobile environment and instead propose a new platform called Limbo based on the tuple space communications paradigm. The design of Limbo is presented together with details of two prototype implementations. The use of the platform to re-engineer a number of existing adaptive mobile applications is also discussed.
