手表式信息设备，即所谓的智能手表，非常适合远程护理服务，因为它们通常靠近用户并且可以持续感知用户活动。然而，由于与智能手机相比，它们仍然是不成熟的设备，因此它们的使用情况和远程护理服务的适用性尚不清楚。在本文中，我们提出并评估了一种使用智能手表和无线生物传感器的点对点（P2P）远程护理系统。特别是，我们在这个基于智能手表的远程护理系统上实现了 P2P 通信协议并评估其通信性能。为了保证智能手表模型的高效实现，我们采用“发布者/订阅者架构”作为智能手表的内部数据处理架构。由于该架构的松耦合、可扩展性，系统可以根据传感器数据的关键字灵活地控制传感器数据的处理和目的地。我们首先描述该系统的概述，该系统使护理人员能够在智能手表上共享护理人员的生理状态。接下来，我们描述 P2P 通信协议及其实现，并展示其在不同网络配置下的通信性能（例如，数据包丢失和延迟时间）的实验结果。结果表明，最新的智能手表加上通信协议的有效实施可以提供远程护理服务。
Wristwatch-type information devices, so-called smart watches, are excellent for telecare services because they are normally close to users and can continuously sense user activities. However, as they are still immature devices compared to smartphones, their usage and applicability for telecare services are not known. In this paper, we propose and evaluate a peer-to-peer (P2P) telecare system using smart watches and wireless biosensors. In particular, we implement P2P communication protocols on this smart-watch-based telecare system and evaluate its communication performance. To ensure efficient implementation of the smart watch model, we use a “publisher/subscriber architecture” as an internal data processing architecture of a smart watch. Owing to the loosely-coupled, extensible nature of this architecture, the system can flexibly control the processes and destinations of sensor data based on their keywords. We first describe an overview of the system that enables care-persons to share the physiological status of the cared persons on smart watches. Next, we describe P2P communication protocols and their implementation, and show experimental results of their communication performance (e.g., packet losses and delay times) in different network configurations. The results shows that the latest smart watches together with efficient implementation of the communication protocols can provide telecare services.
