Abstract

The invention relates to the technical field of communication, in particular to an MAC (Media Access Control) layer ARQ (Automatic Repeat Request) retransmission dynamic adjustment method based on tactical Internet, which comprises the following steps of: setting a service type in an application layer of a tactical data link TTNT, formulating a grouping technique rule of the service type, and adding service type information of the application layer into a packet header field for lower-layer analysis; the application layer service type information is introduced into a traditional automatic repeat request (ARQ) mechanism of a data link layer and is used for judging which service type the current repeat service belongs to; and the data link layer dynamically adjusts the retransmission times according to the type of the current service. According to the invention, the mode of introducing the service information type of the application layer to the traditional automatic repeat request (ARQ) of the data link layer is adopted, and the repeat times are dynamically adjusted according to different service types, so that the time delay of network transmission is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a MAC layer ARQ retransmission dynamic adjustment method based on tactical Internet. Background technique [0002] The rapid development of electronic information technology has given birth to a new military revolution around the world, and the construction of informationized army and informationized weapons and equipment has become the core content of this new military revolution. In the process of informatization, as a standard communication link for transmitting tactical digital information between different combat units, the tactical data link plays a vital role on the modern battlefield. [0003] Tactical data link is one of the important symbols of the development of information warfare, and the application level of tactical data link determines the level and capability of information warfare to a large extent. With the communication network as the link and informati...
