Problems solved by technology

This compression scheme destroys the hierarchical nature of the protocol. The HC1 byte is followed by the HC2 byte, and then all uncompressed fields in the next protocol header such as IPv6 header and UDP are all stored together, although the uncompressed fields have a certain amount of storage. sequence, but this compression method destroys the hierarchical structure of the network protocol, making it inconvenient to parse and process

Embodiment Construction

[0046] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0047] like figure 2 As shown, it is a flow chart of a method for compressing an IP header in an embodiment of the present invention. The IP header includes: an identification field, an uncompressed field, and a header field of the next header, and the specific steps are as follows:

[0048] Step 201, according to the type of the source address in the IP header and the type of the destination address, respectively compress the source address field and the destination address field of the IP header;

[0049] In this embodiment, the type...

Abstract

The invention provides a method and a device of compression of an internet protocol (IP) masthead. The method of the compression of the IP masthead comprises the following steps: step A, carrying out compression on source address fields and destination address fields of the IP masthead according to the type of a source address and the type of a destination address in the IP masthead; step B, carrying out compression on transmission type fields and flow label fields in the IP masthead according to a transmission type and a flow label in the IP masthead; and step C, carrying out compression on first part fields of a next masthead in the IP masthead according to a first part type of the next masthead in the IP masthead. The IP masthead which is compressed satisfies a hierarchical structure of an internet protocol through compression so as to facilitate subsequent analysis and processing.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for compressing IP headers of a sensor network based on 6LoWPAN (IPv6 over Low power WPAN). Background technique [0002] In recent years, with the rapid progress of microelectronic technology, computer technology, wireless communication technology and sensor technology, the rapid development of wireless sensor network technology has been greatly promoted. A wireless sensor network is a wireless network composed of a group of randomly distributed micro-sensor nodes integrated with sensors, data processing units and communication modules in a self-organizing manner. Its purpose is to cooperatively sense, collect and process the information of the sensed objects within the coverage of the network, and transmit it to the information acquirer. At present, sensor network technology has been widely used in the fields of national defense ...
