项目摘要

This research provides following results, which are correspond to an original research objective. First, the research has clarified importance of low-power and low-cost device cooperation mechanisms to realize ubiquitous computing environment, and has proposed a device cooperation mechanism, called as ANTH (Antennary Thing), based on event driven service description. Next, the research has developed and evaluated a bind control model, which is for implementing the event driven service description with compactness. The bind control model manages functions on objects with ID, which is assigned to each function. The research also has proposed, developed, and evaluated an event-oriented network, which is upper layer technology on ANTH. The event-oriented network enables the users to build various services with combining sensor and context. Finally, the research has proposed, developed, and evaluated adaptive media access control protocols, which are under layer technology of ANTH. The media access control protocols include a scalable device discovery protocol and a wakeup wireless module.This research also provides a following result, which is beyond the original research objective. The research has faced a need to support hard real-time tasks for future ubiquitous computing environment. To this end, the research have studied and developed a compact hard real-time operating system, called as PAVENET OS. PAVENET OS can support various applications, which are beyond the device cooperation mechanism. Some research is already started, and the research includes earthquake monitoring and wireless networked control systems.

本研究提供了以下结果，与最初的研究目标相一致。首先，阐明了低功耗、低成本的设备协作机制对实现普适计算环境的重要性，提出了一种基于事件驱动的服务描述的设备协作机制Anth(Antennary Thing)。其次，本研究开发并评估了一个绑定控制模型，该模型用于实现紧凑的事件驱动的服务描述。绑定控制模型管理具有ID的对象上的函数，该ID被分配给每个函数。本研究还提出、开发和评估了一种面向事件的网络，这是一种基于ANTH的上层技术。面向事件的网络使用户能够构建结合传感器和上下文的各种服务。最后，提出、开发和评估了ANTH底层技术中的自适应媒体访问控制协议。媒体访问控制协议包括可扩展的设备发现协议和唤醒无线模块。本研究还提供了以下结果，超出了最初的研究目标。这项研究面临着为未来泛在计算环境支持硬实时任务的需求。为此，本研究研究开发了一种紧凑型硬实时操作系统PAVENET OS。PAVENET操作系统可以支持设备协作机制之外的各种应用。一些研究已经开始，研究包括地震监测和无线网络控制系统。
