物联网作为新一代信息技术的重要组成部分,也是数据时代的重要发展阶段。物联网的概念最早是由美国自动识别实验室在1999年提出的,国际电信联盟曾在2005年的世界信息峰会上发布《ITU互联网报告2005:物联网》,才正式提出"物联网概念",其英文名称"Internet of things (IoT)"。而物联网网关正在成为将传统和下一代设备引入物联网(IoT)的关键要素,是把分散在不同地域、不同应用的感知网络的信息孤岛通过电信网络连接在一起,实现了异构网络间的信息交换和通信,实现"可运营、可管理"的物联网的关键网元设备。文章在研究物联网的发展趋势的基础上,首先对物联网技术进行了详细的表述,以及物联网网关的接入的主要技术和场景业务;最后在此基础上,从硬件和软件两个方面对于物联网网关设计进行分析,探讨如何实现不同感知设备的接入。 相似文献

The challenge raised by the introduction of Internet of Things (IoT) concept will permanently shape the networking and communications landscape and will therefore have a significant social impact. The ongoing IoT research activities are directed towards the definition and design of open architectures and standards, but there are still many issues requiring a global consensus before the final deployment. The paper presents and discusses the IoT architectural frameworks proposed under the ongoing standardization efforts, design issues in terms of IoT hardware and software components, as well as the IoT application domain representatives, such as smart cities, healthcare, agriculture, and nano-scale applications (addressed within the concept of Internet of Nano-Things). In order to obtain the performances related to recently proposed protocols for emerging Industrial Internet of Things applications, the preliminary results for Message Queuing Telemetry Transport and Time-Slotted Channel Hopping protocols are provided. The testing was performed on OpenMote hardware platform and two IoT operating systems: Contiki and OpenWSN. 相似文献

Internet technology is very pervasive today. The number of devices connected to the Internet, those with a digital identity, is increasing day by day. With the developments in the technology, Internet of Things (IoT) become important part of human life. However, it is not well defined and secure. Now, various security issues are considered as major problem for a full-fledged IoT environment. There exists a lot of security challenges with the proposed architectures and the technologies which make the backbone of the Internet of Things. Some efficient and promising security mechanisms have been developed to secure the IoT environment, however, there is a lot to do. The challenges are ever increasing and the solutions have to be ever improving. Therefore, aim of this paper is to discuss the history, background, statistics of IoT and security based analysis of IoT architecture. In addition, we will provide taxonomy of security challenges in IoT environment and taxonomy of various defense mechanisms. We conclude our paper discussing various research challenges that still exist in the literature, which provides better understanding of the problem, current solution space, and future research directions to defend IoT against different attacks. 相似文献
