Recent technological advancements have led to the production of arrays of miniaturized sensors, often embedded in existing multitasking devices (e.g., smartphones, tablets) and using a wide range of radio standards (e.g., Bluetooth, Wi-Fi, 4G cellular networks). Altogether, these technological evolutions coupled with the diffusion of ubiquitous Internet connectivity provide the base-line technology for the Internet of Things (IoT). The rapid increase of IoT devices is enabling the definition of new paradigms of data collection and introduces the concept of mobile crowd-sensing. In this respect, new sensing methodologies promise to extend the current understanding of the environment and social behaviors by leveraging citizen-contributed data for a wide range of applications. Environmental sensing can however only be successful if all the heterogeneous technologies and infrastructures work smoothly together. As a result, the interconnection and orchestration of devices is one of the central issues of the IoT paradigm. With this in mind, we propose an approach for improving the accessibility of observation data, based on interoperable standards and on-device web services.
最近的技术进步促使了一系列小型化传感器的产生，这些传感器通常嵌入到现有的多任务设备（如智能手机、平板电脑）中，并使用多种无线电标准（如蓝牙、Wi-Fi、4G蜂窝网络）。总体而言，这些技术发展与无处不在的互联网连接的普及相结合，为物联网（IoT）提供了基础技术。物联网设备的迅速增加使得新的数据收集范式得以定义，并引入了移动群体感知的概念。在这方面，新的传感方法有望通过利用公民贡献的数据来扩展当前对环境和社会行为的理解，以用于广泛的应用。然而，只有当所有异构技术和基础设施协同顺畅运行时，环境传感才能取得成功。因此，设备的互连和编排是物联网范式的核心问题之一。考虑到这一点，我们提出了一种基于可互操作标准和设备上的网络服务来提高观测数据可访问性的方法。
