Abstract

The invention relates to a header compression method applicable to a wireless ad hoc network, and belongs to the field of the design of communication network protocols. The method reduces the cost forsending an IP, TCP or UDP message to a wireless channel and improves the utilization rate of the wireless channel by performing the compression of header information on the sent IP, TCP or UDP message at a source node of the wireless ad hoc network; and a target node performs decompression reduction on head information of a received compressed message so as to realize header compression and decompression functions which are transparent to an upper layer. The strategy of integrally transmitting change fields is adopted, and the association among continuous data packets does not need to be considered, so the method can furthest resist the influence of message loss caused by error code and the like on the performance of the compression method, and has strong reliability and robustness.

Description

A header compression method suitable for wireless ad hoc networks technical field The invention relates to a header compression method suitable for wireless ad hoc networks. The method can realize the compression and decompression of IP, TCP and UDP protocol headers in the multi-hop wireless ad hoc network, thereby reducing transmission overhead in the wireless channel and saving precious bandwidth resources of the wireless channel. The method realizes the functions of protocol header compression and decompression, and can resist the environment of high bit error and high collision loss rate of the wireless channel. It is a robust and reliable header compression method, and is applicable to various multi-hop wireless networks. Background technique With the development of information and network technology, wireless and mobile communication are increasingly used by users due to their flexible and convenient advantages. In terms of civilian use, technologies such as IEEE802...
