由于物联网的迅速发展，无线通信系统中终端节点数量迅速增加。基于此，国际标准化机构IETF组织专门制 定了适用于物联网通信的6LoWPAN标准。该标准将IPv6 协议运行在传统IEEE802.15.4 标准之上，使得系统能够容纳海量的 终端，同时基于不同底层硬件节点能够通过IP 协议进行互联。本文对6LoWPAN标准在物联网中的应用场景和框架以及 6LoWPAN中分片重组、报头压缩、路由转发和安全性进行了研究分析。

Due to rapid development of IOT, the number of sensors increases dramatically in communication system. Based on this, IETF formulates the 6LoWPAN standard for IOT communication. This standard runs the IPv6 protocol based on the conventional IEEE802.15.4, so that numerous number of terminals will be available, and the communication between sensors with different hardware will be feasible. This paper discusses on the scenario and architecture of 6LoWPAN in IOT system, as well as its segmentation, header compression, routing and security issues.
