基于LoRa标准的MAC层协议研究

MAC layer protocol research and implementation based on LoRa

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。

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