基于LoRa标准的MAC层协议研究

物联网技术的发展已经经历了很多年,但是目前大多数物联网的互联仍在依靠互联网和移动互联网,专用于物联网的网络协议缺失,这在一定程度上制约了物联网的大规模普及.以LoRa为代表的低功耗、远距离网络技术的出现,有效解决了物联网复杂组网和超高功耗的难题.针对物联网互联的相关技术进行了探讨,介绍了超窄带物联网技术及低功耗广域网,并主要研究了LoRa技术的MAC层协议,详细论述了该协议的实现过程.

MAC layer protocol research and implementation based on LoRa

The development of Internet of things has undergone a number of years. However, most of the network connectivity of Internet of things is still rely on the Internet and mobile Internet, the network protocol dedicated Internet of things is missing, this restricted the mass popularity of Internet of things to a certain extent. LoRa represented in low-power, long-distance network technologies appears to effectively solve the complex networks and ultra-high-power networking problems. In this paper, the Internet of things were discussed with related technologies, the paper has introduced the ultra-narrow-band technology and low power WAN, mainly study on MAC layer protocol based on LoRa, and discussed in detail about the implementation of the protocol.
