Problems solved by technology

With the diversity of data in the network, the required services are also complicated. Although there are QoS standards in IPv4, the real-time data that needs to be transmitted in real time still depends on the service type field in the protocol at this stage, and Message identification, and this kind of message identification usually uses UDP or TCP port, and the service type field of IPv4 has very limited functions, and will be redefined after a period of time

Embodiment Construction

[0024] 1. Architecture

[0025] Although IPv6 has various advantages, it has no advantages because it is a protocol stack designed for the Internet.

[0026] Taking into account some limitations of the Internet of Things itself, such as bandwidth limitations, limited energy, processors are not powerful, etc., so these two networks must be modified to a certain extent if they want to be truly integrated.

[0027]Therefore, when we design the Internet of Things based on IPv6, we must consider comprehensively. It must not only reflect the incomparable advantages of the IPv6 protocol, but also take into account some characteristics and limitations of the sensor network. The node architecture design must be able to meet the cost. Low power consumption, easy networking and other aspects, we design a general architecture based on the above points, such as figure 1 shown.

[0028] The physical layer defines the interface between the physical wireless channel and the MAC sublayer, an...

Abstract

The invention relates to a next-generation internet protocol header compression method based on an internet of things, which analyzes and learns a frame structural form that the data link layer of the internet of things adopts and designs header compression algorithm in a sensor network which adopts an IPv6 protocol as the main communication protocol, for the characteristics of limited energy and diversified data of the internet of things; the algorithm introduces a concept, i.e. a control domain so as to compress some fields in a traditional header format, simultaneously considers the characteristic of rich data types of the internet of things, well weighs the two contradictory factors, i.e. guarantee and limited energy of QoS, and lays good foundation for the connection of the internet of things and the next generation of internet.

Description

technical field [0001] The present invention is used in one of the key technologies in Internet of Things and next-generation Internet (Internet) interconnection, the next-generation Internet protocol, that is, IPv6 header compression. It mainly solves how to use the simplified IPv6 header format for communication between nodes in the Internet of Things, which belongs to the cross field of Internet of Things and Internet communication protocol configuration. Background technique [0002] In my country's "Eleventh Five-Year Plan for Information Industry Science and Technology Development and 2020 Medium and Long-term Plan (Outline)", "intelligent information processing and thing-to-thing communication network technology" is identified as one of the 11 main technical fields in the field of network and communication. And it is determined as the core technology that our country needs to focus on breakthroughs. Its development goals include "emphasizing the research and developmen...
