Embodiment Construction

[0052] The header compression method suitable for wireless ad hoc networks adopts a segment-by-segment compression and decompression mechanism, and its implementation is mainly divided into two parts: the connection establishment process and the compression and decompression process, which are described in detail below:

[0053] In a packet network, a communication between a source node and a destination node is called a connection. A large amount of data may need to be exchanged between the source and the destination in a connection, and these data are divided into individual messages, which are transmitted from the source node to the destination node one after another. A connection sends a message each time, and when all the messages in a connection have been transmitted after multiple transmissions, the connection ends. The headers of multiple packets belonging to the same connection have the same field information, or the relevant information in other subsequent packet hea...

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 for sending 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

technical field [0001] 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 [0002] 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 civil use, technologies such as IEEE802.11 and wimax will exist as a part of the 3G network in...
