Abstract

The invention discloses a 6LoWPAN (IPv6 over Low power Wireless Personal Area Network)-based network connection method. The 6LoWPAN-based network connection method comprises the following steps: on the basis of LwIP, establishing a 6LoWPAN+RPL protocol stack model including an application layer, a transmission layer, an IP layer and a physical layer; and increasing a 6LoWPAN adaptation layer between the IP layer and the physical layer to complete MAC management, and frame compression, frame fragmentation and frame recombination of 6LoWPAN. The invention also discloses a 6LoWPAN-based network connection system. The 6LoWPAN-based network connection method establishes the 6LoWPAN+RPL protocol stack model including the application layer, the transmission layer, the IP layer and the physical layer on the basis of LwIP, and increases the 6LoWPAN adaptation layer between the IP layer and the physical layer to enable nodes and gateways to have higher communication efficiency. And the 6LoWPAN-based network connection method supports fragmentation and recombination of MAC data frames, and can send data with random lengths.

Description

technical field

[0001] The present invention relates to the technical field of wireless communication, in particular to a 6LoWPAN-based network connection method and system thereof. Background technique

[0002] In the field of the Internet of Things, wireless communication technologies mainly include manufacturer-defined radio frequency and IEEE 802.15.4 standard radio frequency. The former radio frequency is related to specific manufacturers, and the compatibility of applications is greatly limited. The latter provides a unified radio frequency standard for IoT applications from different manufacturers. For a long time, the radio frequency and network layer specifications based on IEEE802.15.4 are based on the zigbee protocol. The zigbee protocol, a non-TCP / IP proprietary protocol, has great restrictions on the direct access of devices to the Internet, and it has always been considered unrealistic to introduce the TCP / IP protocol into the IEEE 802.15.4 wireless communica...
