Problems solved by technology

In 2012, the 6LoWPAN working group completed the research work on the adaptation layer, but its adaptation layer only supports the 802.15.4 protocol standard
This method necessarily requires the IoT gateway to be able to compress and decompress the IPv6 data header at the network layer, and the compression efficiency is limited by many conditions, which directly affects the effective data transmission rate.

Abstract

The invention discloses a method for accessing an IPv6 network based on a connection identifier for a heterogeneous Internet of Things node, including: step 1, initializing an Internet of Things node N; automatically configuring an IPv6 address, and constructing an IPv6 data header by removing redundant fields and The session layer PDU composed of the transport layer header of the redundant field, and completes the Init message encapsulation and transmission; step 2, the IoT gateway G and the IoT node N complete the negotiation of the connection identifier ConnID, and at the same time establish the network communication parameter-connection identifier ConnID Mapping table; based on the negotiated connection identifier ConnID, the IoT node N completes the encapsulation and transmission of subsequent Data messages. The present invention can carry out communication in a global scope based on the IPv6 protocol, and at the same time ensure that the data frame has a more stable and higher effective data transmission rate.

Description

technical field [0001] The present invention relates to the field of IPv6 Internet of Things, in particular to a method for accessing IPv6 network of heterogeneous Internet of Things nodes based on connection identifiers. Background technique [0002] The application of the IPv6 protocol in the field of the Internet of Things is the general trend. The massive address space provided by the IPv6 protocol can effectively meet the needs of the node identification of the Internet of Things. At the same time, the IPv6 protocol simplifies the address allocation mechanism, header options, and router packet processing, and provides better mobility. Support, security support and automatic authentication functions. [0003] Internet of Things nodes access the Internet based on the IPv6 protocol, and the effective transmission of Internet of Things node data information on the IPv6 Internet is the fundamental guarantee for promoting the development of the Internet of Things. However, u...
