由于应用程序的工作环境不断变化，因此为诸如移动的ad hoc网络（MANET）的高度动态环境编程应用程序是复杂的。本文提出了“视图”的抽象表示和维护上下文信息，定制的应用程序在MANNETWORK。应用程序代理可以通过声明性地描述它感兴趣的上下文信息来定义视图。一个支持的中间件平台，称为ObjectPlaces，确保由视图表示的信息不断反映代理的上下文信息，尽管在MANET中的动态情况。详细介绍了ObjectPlaces用于维护视图信息的分布式协议，并给出了一个全面的评价。
Programming applications for highly dynamic environments such as mobile ad hoc networks (MANETs) is complex, since the working context of applications changes continuously. This paper presents "views" as abstractions for representing and maintaining context information, tailored to applications in MANETs. An application agent can define a view by declaratively describing the context information it is interested in. A supporting middleware platform, called ObjectPlaces, ensures that the information represented by a view continuously reflects the agent's context information, despite the dynamic situation in a MANET. We elaborate on the distributed protocol that ObjectPlaces uses to maintain the information of views, and give a thorough evaluation.
