A Study on Low-power and Low-cost Device Cooperation Mechanism

本研究提供了以下结果，这些结果与最初的研究目标相对应。首先，研究明确了低功耗、低成本的设备协作机制对实现泛在计算环境的重要性，提出了基于事件驱动服务描述的设备协作机制ANTH （antenary Thing）。其次，研究开发并评估了一个绑定控制模型，该模型用于实现具有紧凑性的事件驱动服务描述。绑定控制模型用ID管理对象上的函数，ID分配给每个函数。该研究还提出、开发并评估了面向事件的网络，这是ANTH的上层技术。面向事件的网络使用户能够结合传感器和上下文构建各种服务。最后，研究提出、开发并评估了自适应媒体访问控制协议，这是ANTH的底层技术。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，这超出了原来的研究目的。该研究面临着支持未来普适计算环境下硬实时任务的需求。为此，本研究研究开发了一种紧凑的硬实时操作系统，称为PAVENET OS。PAVENET操作系统可以支持各种应用程序，这些应用程序超出了设备协作机制。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。

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.
