A HF Ad Hoc Network Simulation System

Abstract

The invention relates to a short-wave ad hoc network simulation system, in particular to a simulation system for the MIL-STD-188-141B protocol, which belongs to the technical field of military communication. The system is suitable for hierarchical design and modeling simulation of the third-generation automatic link establishment algorithm in the protocol in OPNET simulation software, including four-layer structure: network layer, subnet layer, node layer and process layer. The network module is located at the network layer, including n shortwave ad hoc network platform models located at the subnet layer. The shortwave ad hoc network platform module is located at the subnet layer, including a shortwave network controller module, a shortwave encryption and decryption module, a shortwave modem module and a shortwave transceiver module at the node layer. These modules are designed for the third-generation automatic link establishment algorithm, so they are suitable for simulation before developing a communication system based on the MIL-STD-188-141B protocol. The modular design is also easy to use and upgrade.

Description

technical field [0001] The invention relates to a short-wave ad hoc network simulation system, in particular to a simulation system for the MIL-STD-188-141B protocol, which belongs to the technical field of military communication. Background technique [0002] Short-wave communication has the advantages of low cost, long communication distance, strong survivability, and good maneuverability. It has been widely used in long-distance, large-scale, mobile communication and other occasions for a long time. It is a very important means of communication. Short-wave communication relies on ionospheric reflection, and the ionosphere is affected by factors such as seasonal climate and time, and is also affected by sunspots, so it is very unstable, which will affect the quality of short-wave communication. In practical applications, the appropriate short-wave communication is usually selected manually. channel to ensure the quality of shortwave communication. [0003] In order to imp...

Problems solved by technology

Since direct evaluation of engineering equipment requires high cost and risk, and some conditions and environments used for evaluation are difficult to achieve ideal conditions, so simulation must be carried out before actual engineering evaluation to make up for direct engineering equipment evaluation and provide a certain theoretical basis for the actual engineering evaluation

OPNET simulation software has provided some standard systems for wireless communication networks, including physical layer, data link layer, network layer, transport layer, application layer, wireless system, some manufacturers' equipment systems, etc., but it has not directly targeted MIL-STD -Simulation method of the third generation automatic link establishment (3G-ALE) algorithm in the 188-141B protocol
