Collaboration Bus for Environment-Adaptive Groupware

日常计算的一个主要趋势是从工作站无缝转移到无线手持设备。 第二个主要趋势是与同事的持续合作。 由于平台和通信网络的巨大差异，证实和支持这些趋势极其困难。 该提案的目标是开发和演示一个中间件框架，用于在异构网络上进行性能优化的无处不在的协作。 它将使服务质量的应用程序和支持选择性的数据分发。 该框架的关键组成部分是协作总线，它是一个中间件，以支持组通信的数据为中心的群件。 研究内容包括：a）动态监测网络性能的算法和方法，B）调整网络流量的数据转换和适配策略，以及c）评估和控制广播每条消息对性能的影响，其中数据适配代理的开发是研究的关键。 这些代理转换和更改数据，以便它可以被不同的应用程序和硬件使用。拟议中的研究将为多用户协作带来新的能力。

A major trend in day-to-day computing involves moving seamlessly from workstation to wireless handheld devices. A second major trend is continuous collaboration with colleagues. Accommodating and supporting these trends is extremely difficult because of the vastly different platforms and communication networks. The objective of the proposal is to develop and demonstrate a middleware framework for performance-optimized ubiquitous collaboration over heterogeneous networks. It will enable quality-of-service applications and support selective data distribution. The key component of the proposed framework is the collaboration bus, which is a middleware to support group communication in data-centric groupware. The proposed research includes:a) algorithms and methods for dynamic monitoring of network capabilities,b) data transformation and adaptation policies for adjusting network traffic, andc) assessing and controlling the performance impact involving in broadcasting each message.Some of the key elements of the research are the development of Data Adaptation Agents. These agents transform and change the data so that it can be used by different applications and hardware. The proposed research will bring new capabilities for multi-user collaboration within reach.
