Adaptive Middleware Services for Situation-Aware Communication in Ubiquitous Computing Environments

分布式计算的一个主要趋势是朝着由大量可穿戴、手持和嵌入式设备组成的环境发展。廉价、短距离、低功耗的无线通信和硬件的快速发展，正在使无处不在的计算环境的实验成为可能。为了使无处不在的环境正常工作，设备必须能够检测其当前上下文，它们必须意识到用户和设备之间的关系，并处理特定组及其通信。该提案计划采用集成的硬件和软件方法来开发基本服务，以支持异构环境中的各种分布式应用程序。这些服务包括对以下方面的研究：态势感知的对象间通信；建立设备社区的组管理服务；使用元胞自动机计算模型设计可扩展的传播服务的可行性；该服务将使用上下文敏感的概念在透明和QoS辅助适应之间进行权衡。该提案将开发一个可重构和上下文敏感的中间件，该中间件将是基于蓝牙标准的开源、开放原理图和开放标准中间件。

A major trend in distributed computing is toward environments consisting of numerous wearable, handheld and embedded devices. Rapid growth in inexpensive, short range, and low-power wireless communications and hardware, are now enabling experimentation with ubiquitous computing environments. In order for ubiquitous environments to work well, it is essential that devices be able to detect their current context, that they must be aware of relationships between the users and the devices, and handle ad-hoc groups and their communications.The proposal plans to take an integrated hardware and software approach to developing essential services to support a wide variety of distributed applications in heterogeneous environments. The services include investigation of:situation-aware inter-object communicationsgroup management service to establish device communitiesfeasibility of using cellular automata computational model to design a scalable dissemination servicea service that will use the concept of context-sensitivity to perform trade-offs between transparent and QoS assisted adaptations.The proposal will develop a Reconfigurable and Context-Sensitive Middleware, which will be open-source, open-schematic and open standard middleware based on top of Bluetooth standards.
