无线传感器网络由数千个智能感知节点组成，这些节点为汇聚节点捕获环境数据。与传统计算机网络相比，这种网络提出了新的挑战，即智能节点的硬件约束和非常有限的能源资源。无处不在的计算可以从无线传感器网络中受益，因为感知数据可以代替用户使用，而无需明确的干预，使无处不在的计算成为现实。无线传感器网络中的互联网连接是非常理想的，具有全球范围的传感服务。考虑了两种主要方法：基于代理或基于传感器节点堆栈。第二种方法将传感器转变为产生数据的主机，也被称为“物联网”。多年来，TCP/IP（传输控制协议/互联网协议）套件被认为不适合wsn，主要是因为这种有限硬件的固有复杂性和协议开销。然而，最近的研究使得将wsn连接到互联网成为可能，即使用基于传感器节点堆栈的方法，使其能够集成到未来的互联网中。本文综述了无线传感器网络与互联网连接的现状，介绍了相关成果，并对如何开发基于ip的无线传感器网络通信解决方案提出了见解。版权所有John Wiley & Sons， Ltd。
Wireless sensor networks (WSNs) are composed of thousands of smart-sensing nodes, which capture environment data for a sink node. Such networks present new challenges when compared with traditional computer networks, namely in terms of smart node hardware constraints and very limited energy resources. Ubiquitous computing can benefit from WSNs from the perspective that sensed data can be used instead of the user without explicit intervention, turning ubiquitous computing into a reality. Internet connectivity in WSNs is highly desirable, featuring sensing services at a global scale. Two main approaches are considered: proxy based or sensor node stack based. This second approach turns sensors into data-producing hosts also known as 'The Internet of Things'. For years, the TCP/IP (Transmission Control Protocol/Internet Protocol) suite was considered inappropriate for WSNs, mainly due to the inherent complexity and protocol overhead for such limited hardware. However, recent studies made connecting WSNs to the Internet possible, namely using sensor node stack based approaches, enabling integration into the future Internet. This paper surveys the current state-of-the-art on the connection of WSNs to the Internet, presents related achievements, and provides insights on how to develop IP-based communication solutions for WSNs today.
