Wireless sensor networks (WSNs) are an interconnection between hundreds to thousands of geographically distributed sensor nodes often called motes. WSNs are deployed in various fields for collecting data; they are used in healthcare monitoring, weather service, civil and military applications, and so on. WSNs are faced with many challenges due to their lack of computational resources, restrained storage capacities, and limited energy resources. The apparition of Cloud computing technology with its many advantages led the idea of integration between these two technologies. In this article, we will present an overview of works related to the interconnection between WSNs to the Cloud. After analyzing the contents of the published works, we established their classification according to the subjects treated. Four items are therefore selected, namely storage and computation, security, application and finally integration for Internet of Things (IoT). This brief review of the literature shows that the development of WSNs-Cloud interconnection solves the problem of minimizing energy consumption at the sensor level, the problem of data storage, as well as the problem of access to the medium.

无线传感器网络与云集成的简要回顾

无线传感器网络 (WSN) 是数百到数千个地理分布的传感器节点之间的互连，通常称为节点。WSNs部署在各个领域以收集数据；它们用于医疗保健监测、气象服务、民用和军事应用等。由于缺乏计算资源、有限的存储容量和有限的能源资源，WSN 面临着许多挑战。云计算技术以其众多优势的出现，催生了这两种技术之间的融合。在本文中，我们将概述与 WSN 与云之间的互连相关的工作。在分析了已发表作品的内容后，我们根据所处理的主题对其进行了分类。因此选择了四个项目，即存储和计算、安全、应用以及物联网 (IoT) 的最终集成。对文献的简要回顾表明，WSNs-Cloud 互连的发展解决了传感器级能耗最小化问题、数据存储问题以及对介质的访问问题。
