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

分布式计算的一个主要趋势是向由大量可穿戴设备、手持设备和嵌入式设备组成的环境发展。廉价、短距离和低功耗无线通信和硬件的快速增长，现在使无处不在的计算环境的实验成为可能。为了让无处不在的环境能够很好地工作，设备必须能够检测它们的当前上下文，它们必须知道用户和设备之间的关系，并处理自组织组及其通信。该提案计划采取硬件和软件集成的方法来开发基本服务，以支持在不同环境中的各种分布式应用。这些服务包括：情景感知对象间通信建立设备社区的组管理服务利用元胞自动机计算模型设计可扩展的分发服务的可行性该服务将使用上下文敏感的概念来在透明和服务质量辅助的适配之间进行权衡。该提议将开发一个可重构的上下文敏感中间件，它将是基于蓝牙标准的开源、开放架构和开放标准的中间件。

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.
